Each G6 chassis must include at least one system control module (SCM), which performs overall control functions and manages the flow of information between the other system modules. An optional second SCM provides system redundancy for the shelf. (This feature will be supported in a later release.) Figure 1 shows the G6 Voice Gateway chassis.

Figure 1. G6 Voice Gateway Chassis

Preliminary Beta Release—Subject to Change 1

G6 Chassis

G6 Chassis The G6 chassis is 13 U (22.75 inches) tall, 17.5 inches wide (without mounting ears). The NEBS compliant version is 12 inches deep, which includes external network connectors (T1 Champs and BNCs) accessible from the rear of the chassis.

Mounting The G6 chassis can mount in a 23-inch or 19-inch (cable and wireless) rack or cabinet, using EIA or WECO standard mounting hole patterns. The card cage can be front-mounted or mid-mounted. Both 23-inch and 19-inch mounting ears are supplied with the unit, with the 23-inch mid-mount being the attached standard.

Cooling The chassis uses forced convection fans to cool from the bottom to the top of the cardcage. The 3-fan assembly (color-coded with purple latches) runs at 40VDC for noise reduction and reliability.

If the environment temperature rises to 41ºC (105ºF) the fan controller increases the rotational speed of the fans to 48VDC. In cases of fan failure (low rpm), the fan controller increases the rotational speed of the remaining fans to 48VDC to compensate. This process maintains a constant air flow throughout the G6 chassis.

An alarm on the fan tray and on the GenView EMS indicates a fan failure. A fully-loaded G6 shelf can run for 20 minutes with a single operating fan or with the fan tray removed, to allow for fan replacement or maintenance.

2 Hardware Installation Guide

Overview

The fan assembly module is hot-swappable and can be removed or replaced with power applied to the chassis. The following chart describes the LEDs on the fan assembly module.

Grounding The chassis includes a frame ground connector (on the back of the NEBS compliant chassis or the front of the ETSI compliant chassis). Frame grounding is effected via a ground wire attached to the rack. The SCM-CI panel on the back of the chassis includes a transient ground connector.

Figure 2. Transient Ground Connector (Chassis Back View)

ESD jacks on the front and back of the chassis provide ESD grounding. Anyone working on the G6 shelf or components should wear and plug in a wrist grounding strap while handling any of the module cards.

Card Cage and Card Slots

A full-populated G6 Voice Gateway includes 2 system control module (SCM) cards and 16 module cards. As many as 14 of the module cards can be telephony port module (TPM) cards. As many as 6 can be access network module (ANM) cards.

ANM cards can be installed in card slots 1–6 and TPM cards in slots 3–8 and 11–18. For each TPM or ANM card in the system, a cable interface module (CIM) card is required in the same slot on the back of the chassis. The partner CIMs for most cards provide the cabling connections out to the telephony network. Cards that support fiber connections include the network connectors on the front of the module card and use CIM blanks.

The cardcage meets GR-63 and GR-1089 requirements and draws a maximum of 425 watts, in compliance with NEBS regulations. A gasket on the side of each telephony card and CIM provides EMI protection for the card.


Overview

System Control Module

The SCM card performs overall system control functions as well as the ATM switching functions. The SCM manages the flow and synchronization of information to the other system modules. A G6 shelf supports a primary SCM card in card slot 9 and a hot standby in card slot 10. In a G6 shelf with redundant SCMs, the standby SCM continuously monitors all system activity and checks the operation decisions of the active SCM. If the standby SCM detects a fault, it assumes active control and removes the previously-active SCM from the bus. The now active SCM in slot 10 generates an alarm for the now inactive SCM in slot 9.

Access Network Module

An access network module (ANM) card provides an interface to an ATM backbone network, digital subscriber line access module (DSLAM), or cable modem termination system (CMTS). ANM cards exchange connection-oriented, variable bit rate AAL2 or AAL5 traffic. AAL2 supports isochronous video or voice traffic over ATM. AAL5 supports IP traffic over ATM or LAN emulation (LANE) for an ATM-based LAN backbone. AAL5 has a low overhead also provides error recovery. ANM cards currently support DS3 framing.

Overview

Figure 6. 4-Port DS3 ANM Card Faceplate

Different CIM cards paired with an ANM card support different framing specifications (DS3, for example), transmission line types (T3 at 44.736 Mbps or E3 at 34.368 Mbps, for example), and network connections (paired BNCs). The 4-port DS3 CIM supports as many as 4 network connections to a DSLAM or an ATM backbone.

ANM Card Redundancy

The ANM cards use a 1:1 sparing scheme for redundancy. Installing a secondary, sparing card (and CIM) provides a redundant ANM interface (hot standby). Each standby ANM card provides hot standby for a single ANM card in the G6 shelf. The hot standby card typically resides in the card slot adjacent to the primary ANM card. A CIM-DS3 card installed along with the standby ANM enables routing of DS3 traffic from a failed

ANM card through the sparing bus to its standby ANM card. A “Y” cable for each DS3 line connects the line to both the active and standby CIM-DS3 card.

ANM Status LEDs

Each 4-port DS3 ANM has 10 faceplate LEDs to provide line and module information. There is one status LED, an active/standby LED, and one transmit and receive port status LED pair for each DS3 line.

Overview

Telephony Port Module

A telephony port module (TPM) provides a high-speed interface to the Public Switched Telephone Network (PSTN) via the GR-303, TR-008, ISDN PRI, or V5.2 line protocol.

Figure 7. DS1/T1 TPM Card Faceplate

Different CIM cards paired with a TPM card support different framing specifications (DS1, for example), transmission line types (T1 at 1.54 Mbps or E1 at 2.048 Mbps, for example), and network connections (Champ for T1 or BNC for E1, for example). The TPM cards and CIMs currently support T1 transmissions using DS1 framing. The CIM-T1 card supports 10 T1 lines.

TPM Card Redundancy

The TPM cards use a 1:N sparing scheme for redundancy. Installing a secondary, sparing TPM card (and CIM) provides a redundant TPM interface (hot

standby). One standby TPM card provides hot standby for all TPM cards in the G6 shelf. The hot standby card typically resides in card slot 18. A CIM-SPARE card installed in slot 18 enables routing of DS1 traffic from a failed TPM card through the sparing bus to the TPM standby card.

TPM Status LEDs

Each T1 TPM has 12 faceplate LEDs to provide line and module information. There is one status LED, an active/standby LED, and one port status LED for each T1 line.

Overview

Cable Interfaces Each ANM or TPM card requires a separate card to provide the electrical and cable interfaces. The two SCM cards have a common cable interface. Cable interfaces support management, network, alarm, and power connections.

SCM-CI Panel The SCM-CI services both the active and standby SCM.The SCM-CI panel includes two management ports with RJ-45 10/100Base-T Ethernet connectors. For redundancy, connect each management port to the GenView EMS via a different LAN. Figure 8 shows the primary (A, on the right) and standby (B) management port connectors on the SCM-CI panel.

Figure 8. A & B Management Ports on SCM-CI Panel


Cable Interfaces

There are 24 fuse and alarm panel (FAP) wire-wrap pins on the SCM-CI to provide 12 relay closures. Each pin contains EMI egress filtering and GR-1089 surge protection. Only the active SCM can send an alarm. Figure 9 shows the audible, visible, and E2A alarm and events pins on the SCM-CI panel.

Figure 9. Alarm and Events Pins on SCM-CI Panel

BITS and CC timing inputs can be connected to the SCM-CI. The inputs are provided on wire-wrap pins. BITS inputs are terminated with 100 ohms. CC inputs are terminated with 133 ohms. Thus, the G6 shelf supports termination even if no SCM cards are present, per GR-1244 requirements. BITS and CC inputs are protected against GR-1089 surge voltages. Figure 10 shows the BITS and CC external timing pins on the SCM-CI panel.


Overview

Figure 10. BITS and CC Timing Pins on SCM-CI Panel

The SCM-CI panel provides a redundant 48V power interface for the chassis. The transformer on the SCM-CI minimizes EMI egress. The power connectors also have intra-building surge protection to meet GR-1089 requirements. Figure 11 shows the power connector block on the SCM-CI panel.

Figure 11. Power Connector on SCM-CI Panel


Cable Interfaces

The following chart summarizes the SCM-CI ports and connectors. An EEPROM on the SCM-CI stores a unique serial ID for the G6 chassis. After installation, the active SCM accesses the EEPROM for this information, and provides it to the GenView Element Management System (EMS).

CIM-DS3 and CIM-DS1/T1 Cards

The CIM-DS3 cards include 4 BNC network interface connectors. Each pair of 75-ohm BNC connectors (transmit and receive) supports one DS3 port. Both receive and transmit DS3 interfaces are differentially surge protected.

The CIM-DS1/T1 cards include a 50-pin Champ network interface connector to support 10 T1 lines. Each T1 interface on the CIM-DS1/T1 contains fuses and primary protection to tolerate lighting and surge protection for external wiring.

Figure 12 shows the CIM-DS1/T1 and CIM-DS3 card connectors.

CautionThe SCM-CI is mounted in the chassis during factory assembly. The SCM-CI cannot be removed from the chassis without taking the entire G6 Voice Gateway out of service. The SCM-CI is not field replaceable.

System Software

The G6 Voice Gateway stores system software in flash memory on the SCM cards, ANM cards, and TPM cards. In a redundant SCM configuration, all software can be dynamically updated without affecting the performance of the G6 Voice Gateway (in service). Two methods are available to dynamically update the system software.

Software can be downloaded via TFTP from a management console at the gateway installation site. The console connects to the serial craft port on the front of the SCM card.

Software can be downloaded via TFTP or through the GenView EMS from a management station at the network operation center (NOC). The management station connects via an Ethernet LAN to the 100Base-T Ethernet port on the back of the chassis.

Overview

Updates to the TPM or ANM system software are also through the craft port or Ethernet port. In-service TPM or ANM system software updates require a redundant TPM or ANM configuration, respectively.

The SCM stores all provisioning information in local nonvolatile memory. In the event of a power loss, the G6 Voice Gateway retains provisioning information.

Installing theChassis

This chapter describes the procedures for installing one or more General Bandwidth G6 Voice Gateway chassis (shelves) into a standard 23-inch or 19-inch mounting rack.

Figure 14. G6 Voice Gateway Chassis (Front View)

Standards Compliance

The G6 Voice Gateway complies with NEBS Level 3 for rack-mounted equipment designed and built for use in an environmentally controlled location, such as a switching center.


Aisle Requirements

The site preparation, safety and installation practices described in this chapter for a G6 Voice Gateway installation are based on the Telcordia Network Equipment Building Standards (NEBS).

Ensure that any additional preparation work not described in this document complies with local building and safety codes and with NEBS, as applicable.

Aisle Requirements

When installing a G6 Voice Gateway shelf into a mounting rack, be sure to allow enough room to access the rear of the unit for wiring/cabling purposes. Also allow enough front aisle space to install the G6 shelves from the front of the rack. Allow a minimum of 12 inches in the rear aisle and 12 inches in the front aisle. Whenever possible, follow the GR-63 aisle requirements.

Rack Requirements

Follow NEBS guidelines for installation distance from the closest surroundings. Also, many installations use a 1-foot rack unit (RU) fuse and alarm panel in the top mounting bay. You can install one, two, or three G6 shelves (Figure 15) in a standard or seismic 7-foot-tall, 19-inch or 23-inch relay rack.

Ventilation Considerations

The fan tray installs horizontally (Figure 14) at the bottom of the G6 Voice Gateway chassis. Leave at least a 1-RU space open below each shelf for proper ventilation.

The air filter tray is below the fan tray. Change the air filter monthly for proper filtration and operation.

The fans in the G6 Voice Gateway maintain a suitable operating temperature for the internal circuitry. Ensure that the air intake vents at the bottom of the chassis and the air exhaust vents on the top sides of the chassis are not obstructed in any way.


Installing the Chassis

G6 Shelf Dimensions (U.S.)

The NEBS compliant G6 Voice Gateway chassis measures 22.75 inches tall × 17.5 inches wide × 11.025 inches deep (58 cm × 45 cm × 28 cm), without cables. The universal height measurement is 13 RU.

Network, power, and alarm cables connect through the rear of the unit. Including the external connectors (Champ for T1 and BNC for DS1) and allowing for cable bend, the depth is 12 inches. The chassis with the installed mounting ears fits into a 23-inch rack, mid mounted. A second set of ears is provided for mounting into a 19-inch rack. Both the 19-inch and the 23-inch ears support either mid mounting or front mounting.

Grounding,Cabling, and

Applying Power

This chapter describes how to ground the General Bandwidth G6 Voice Gateway chassis and then apply power to the G6 shelf.

Power Requirements

The G6 Voice Gateway uses a distributed power system. The midplane busses the power mains (redundant –48 VDC A and B rails) to each functional module in the chassis. Each module contains a DC/DC power circuit to convert the –48 VDC to the levels required by the components on that module. In the event of a power failure in the common power circuit on a module, the failure is isolated to the defective module and the module’s functionality is transferred to other resources in the system.


Do not work on the system, connect cables, or dis-connect cables during periods of lightning activity.

Before working on equipment that is connected to power lines, remove jewelry (including rings, neck-laces, and watches). Metal objects will heat up when connected to power and ground and can cause seri-ous burns or become welded to the terminals.


Grounding Requirements

Grounding Requirements

There are three grounds in the G6 Voice Gateway: frame ground, logic ground, and transient ground. The chassis includes frame ground for electromagnetic interference (EMI) suppression. The chassis has frame ground in the mounting holes, RJ-45 shields, BITS shields, and the outer layer of the sheet metal. Logic ground protects the logic components. Logic and frame ground are AC coupled on the midplane.

Transient ground provides lightning and surge protection for the G6 Voice Gateway. The G6 CIMs contain protection circuits for transient ground. The rack in which the G6 shelf is mounted must be connected to earth-ground.

Safety Guidelines





Ground the G6 Shelf



Ground the G6 Shelf

When installing a chassis, always connect the frame ground before any other connections. Always disconnect the frame ground last. Figure 16 shows frame grounding.

1 Connect the grounding wire packaged with the chassis to the metal grounding lug on the chassis.

2 Connect the other end of the grounding wire to the rack. This provides frame ground to the chassis.

Caution!

Allow only trained and qualified personnel to install or replace this equipment.

WARNING! ELECTRICAL HAZARD

Before connecting or disconnecting ground wires to the chassis, ensure that power is removed from the DC circuit. Use a voltmeter to test for 0 (zero) voltage at the power terminals on the chassis.

Caution!

If the rack is painted, ensure that all paint has been scraped off at the point of the grounding connection.

NoteIf the rack is painted, ensure that all the paint has been scraped at the point of the ground-ing connection.



Figure 16. Frame Ground Connection to the Rack

Connect (wire wrap) a transient ground wire from the transient grounding block on the chassis to the building transient ground.

Figure 17. Transient Ground Connectionl

3 Use an appropriate tie-wrap to tie down the transient ground cable to the chassis. Label the cable.

4 Use a digital multimeter (DMM) to verify the ground.

5 Touch a digital multimeter (set to resistance, Ω) to an unpainted part of the chassis and to the common ground in an unpainted part of the rack to verify that the chassis is grounded. (If the multimeter is set for sound, the beep indicates a good ground. Otherwise, visually check to ensure that a ground connection is made.)


Connect the G6 Alarms

Connect the G6 Alarms

This procedure shows how to connect the alarms on the G6 shelf to a fuse and alarm panel that is properly connected to the aisle alarm system. Use a cable stripper and wire-wrap tool to prepare and connect the cables.

The SCM-CI includes 24 fuse and alarm panel (FAP) wire-wrap pins, providing 12 relay closures. Each pin contains EMI egress filtering and GR-1089 surge protection.

The audible alarms are set up to connect (through the fuse and alarm panel) to a horn or other audible alarm device at the installation site. The alarm cut off button (ACO) on the SCM card turns off an audible alarm. The visual alarms connect to aisle lights or other visible alarm devices at the installation site. The E2A alarms provide input to the management stations via the EMS.

The SCM-CI busses the alarms together from both SCMs in a redundant controller configuration. Only the active SCM can send an alarm.

Follow these steps to connect the G6 Voice Gateway alarms to the alarm connectors on the fuse and alarm panel (FAP).

1 For the critical audible alarm, connect an alarm wire from pin 1 (+ high) on the audible alarm block on the chassis to the corresponding alarm pin on the FAP.

2 To complete the relay, connect a second wire from pin 2 (– low) to the corresponding alarm pin on the FAP.

Follow these steps to connect the G6 Voice Gateway management ports to the management stations and management consoles on the primary and redundant LANs. Figure 19 shows the management port connections to the LANs.

1 Connect the Ethernet RJ-45 connector for the primary LAN connection to management port A (labeled 10/100-A) on the SCM-CI panel on the back of the chassis.

2 Connect the Ethernet RJ-45 connector for the redundant LAN connection to management port B (labeled 10/100-B).

3 Use an appropriate tie-wrap to tie down the Ethernet management cables to the chassis. Color code and/or label the cables to identify them as Management Ports A and B.



Figure 19. A & B Management Ports on SCM-CI Panel

Connect the External Timing Ports

A building interface timing system (BITS) provides a T1-formatted signal to carry timing. BITS is the preferred and most reliable timing source for a gateway. The A and B blocks provide redundant timing pins for both SCMs in a chassis. Figure 20 shows the external timing pins on the SCM-CI panel on the back of the chassis. Figure 21 shows an example of timing pins connected to the BITS.


Connect the External Timing Ports


Follow these steps to connect the external timing pins on the G6 Voice Gateway to a BITS.

1 Connect a timing wire to the primary tip timing pin (TIP on the A timing pin block).

2 Connect a timing wire to the primary ring timing pin (RING on the A timing pin block).

3 Connect a timing wire to the primary sleeve timing pin (SLEEVE on the A timing pin block).

4 Connect the primary tip timing wire to the primary tip pin on the timing panel.

5 Connect the primary ring timing wire to the primary ring pin on the timing panel.

NoteConsult the wiring standards for your installation to determine sleeve wire ter-mination requirements. Many installa-tions use a bare wire and terminate it only at the source.



6 Connect the primary sleeve timing wire to the primary sleeve (shield) pin on the timing panel.

7 Repeat steps 1 through 7 for the redundant timing pins.

8 If appropriate for your installation, bundle the timing cables together. Use an appropriate tie-wrap to tie down the timing cable bundle to the chassis. Label the cables to identify them.

Timing can also be provided externally from a T1/DS1 line, a DS3 line, or from a composite clock (CC). If timing is from a T1 or DS3, the G6 Voice Gateway receives the timing from a line connected to a T1 or DS3 port without further connections.

If BITS is connected, any simultaneous T1 and DS3 timing sources are secondary. The gateway does not support simultaneous BITS and CC timing sources.

If timing is from a CC, connect the timing pins exactly as described in the previous steps, but connecting the CC timing pins to the composite clock instead of to the BITS.

If all external timing sources are lost, the G6 Voice Gateway bases timing on the last source for up to 28 hours to allow for maintenance or updates to the timing system.


Connect the G6 Shelf to the Power Source



Before connecting the G6 shelf to the power source, verify that the power source is properly grounded and falls within the internal power supply ratings. The input –48V supply bus is protected by circuit breakers mounted on the rear lower panel of the G6 shelf. Each power supply has an internal major fault circuit protection fuse soldered in place (factory replaceable only) and rated at 25 A, 125 V. The G6 shelf incorporates a power supply monitor to monitor the power supply levels in each of the modules and manage the main hardware reset function on each module.

This procedure shows how to connect the power on the G6 shelf through a fuse and alarm panel that is properly connected to the power source. Using a small flat-head



screwdriver and the appropriate power wires, follow these steps to connect the G6 shelf to the power connectors on the fuse and alarm panel. Figure 22 shows the power connectors on the SCM-CI panel of the chassis.

1 Connect the negative (black in many systems) wire from the Rail A primary power source to the primary negative connector (A) on the power terminal block on the SCM-CI on the back of the chassis.

2 Connect the positive (red in many systems) wire from the Rail A primary power source to the primary positive connector (A-RTN) on the power terminal block.

Figure 22. Power Connectors on the SCM-CI Panel

Detail of primary (A) power connection



3 Connect the negative wire from the Rail B secondary power source to the secondary negative connector (B) on the power terminal block.

4 Connect the positive wire from the Rail B secondary power source to the secondary positive connector (B-RTN) on the power terminal block.

5 If appropriate for your installation, bundle the power cables together. Use an appropriate tie-wrap to tie down the power cable bundle to the chassis. Label the cables as primary and secondary.

Figure 23 shows the G6 shelf connections to a –48VDC power source through an in-rack fuse and alarm panel.

Start Up the System

When a G6 Voice Gateway is shipped, the G6 system software is already installed on the SCM, ANM, and TPM cards. Access to this software is through a command line interface (CLI) provided on the SCM. Refer to the Software Installation & System StartUp Guide for information about starting up a G6 shelf. Refer to the CLI Operation Guide & Commands Reference for a list of the commands available and detailed information about using them.

Run Diagnostics

Use the General Bandwidth System Diagnostics to troubleshoot the G6 shelf installation.

Cable the Telephony Ports

The final physical step in installing a G6 Voice Gateway hardware is to connect the gateway into the network. The physical connections into the network are dependent on the equipment in a particular environment. In general, these physical connections consist of cabling G6 Voice Gateway to the network side (typically a Class 5 switch) and, ultimately, to the customer premises equipment.

Connect to the Network Side

Connecting to the network side typically consists of connecting the DS1/T1 ports to a Class 5 switch. The 50-pin connector on the TPM DS1/T1 CIM provides connections for 10 DS1/T1 ports. The bottom 4 pins (wires) provide T1 #10, the second, T1 #9, and so forth. The top 10 pins are not used.

2 If appropriate for your installation, use an appropriate tie-wrap to tie down the DS1/T1 cable to the chassis. Label the cable.

3 Following the color-coding scheme shown in the Color Coding Wire Scheme section, connect the first set of 4 wires for a T1 (usually T1 #1 or T1 #10) to the Class 5 switch. This connection may be a punchdown box, wire-wrap pins, DSX panel, multiplexer, channel bank, or other connection panel.

4 Follow the color-coding scheme to connect the appropriate four wires for each of the other 9 T1 ports. Connecting all 10 ports uses 40 of the wires in the DS1/T1 cable.

Color Coding Wire Scheme

The wiring illustrations in this section are based on the AT&T uniform color-coding scheme telephony wires. To simplify color coding large numbers of wires, each wire pair uses a two-color code with colors selected from two groups of five. The colors for a group are white, red, black, yellow, and violet. The colors for pair (within a group) are blue, orange, green, brown, and slate.

Caution!

The recommended bend radius for thin-type 735A coaxial cable or equivalent is not less than one-quarter of an inch. A sharper bend can result in the cable not working properly. Do not bend the DS3 cables at a sharper radius than one-quarter of an inch.



Each pair includes one wire with a solid background of its group color and stripes of its pair color. The second wire in the pair reverses the colors. Note that red-brown and red-orange wires are very similar.
