1.1 Introduction

The 7302 ISAM is a frame based Digital Subscriber Line Access Multiplexer(DSLAM), that is, a Digital Subscriber Line (DSL) access multiplexer which isbased on a frame forwarding architecture in a packet aggregation network.

General Network Topology

Figure 1-1shows the basic network topology:

Figure 1-1 General network topology

User Side

At the user side, each 7302 ISAM terminates DSL links and a limited number of FEor GE links.

It is possible to connect subtending DSLAMs to the FE/GE links at the user side in:

cascading mode: a chain of 1 subtending ISAM per ISAM star mode: multiple subtending ISAMs per ISAM ring mode (except when there is a ring behind a Hub-ISAM).

Figure 1-2shows the cascading topology.

Network Side

At the network side, the 7302 ISAM terminates GE or FE links. The followingconfigurations are possible:

Connected to one or more Ethernet SwitchesThe Ethernet links can be connected to one or more Ethernet Switches. TheseEthernet Switches forward the frames over the Ethernet based aggregation accessnetwork until they reach the IP Edge Router or BRAS of the correspondingNetwork Service Provider (NSP). At the IP Edge Router or BRAS, the framesenter the IP backbone of the NSP.

More than one FE/GE link (link aggregation)In case of more than one FE or GE, Ethernet link aggregation is used.

Directly connected to an IP Edge RouterThe 7302 ISAM can be connected directly to the IP Edge Router or BRAS. TheEthernet aggregation network is reduced to one or more parallel Ethernet links.

Note:A link is a term which is used to refer to the physical layer of an interface ofthe 7302 ISAM, for example, an ADSL link, an Ethernet link.

1.4 ISAM with integrated Voice-band services

The ISAM with integrated Voice-band services (ISAM-V) provides support ofPOTS and ISDN services and connection to Next Generation Voice Networks(NGVN) via Voice over IP (VoIP).

Network Architecture

Figure 1-5shows the position of the ISAM-V in the NGVN.

Figure 1-5 Network Architecture

The ISAM-V acts as an Access Media Gateway (MG) and connects the legacyNarrowBand (NB) user interfaces (Plain Old Telephone Services (POTS) andIntegrated Services Digital Network (ISDN)) to the NGVN.

The ISAM-V supports: mixed configurations, where the NB user interfaces and MG Interface are integrated

in the same node

centralized configurations, where the MG Interface is located in a hub node and theNB user interfaces in remote nodes.

The trunk MG links the NGVN with a Legacy network. The softswitch is responsible for call control and charging, and communicates

with the MGs:

via the Media Gateway Control (MEGACO) protocol (ETSI RFC 3525 / ITU-TH.248) for POTS

via the SIGTRAN Control protocol for ISDN

Note H.248.16 (XDD Buffering) is also supported

Basically, XDD buffering is used in order not to lose digits when aftermatching with a valid dialplan the user still continues dialling. WhenXDD buffering is active, detected digits are kept in IVPS in a bufferas a digit string up to a timer expiration or when a new matching withthe current valid dialplan happens.

1 System Overview



Product Architecture

The ISAM Voice Package architecture is that of the ISAM with the addition of voiceservices, which translates into the addition of three boards:

one server board: IVPS, which is the VoIP gateway for ISAM-V

Note: the IVPS is plugged in an LT position, but performs server functions. two LIM boards:

POLT board, providing POTS interface connectivity BALT board, providing ISDN Basic Access (ISDN BA) interface connectivity

Architecture View

The following applies for the ISAM-V product architecture:

ISAM-V nodes are connected to an EMAN An ISAM-V node integrates either:

the server card, IVPS, performing the signaling and OAM functions of the GW

a number of NB LTs cards (POLT-A and BALT-A) performing the media functions both types together

MEGACO and SIGTRAN signaling and external voice service OAM areterminated at IVPS

Internal control and signaling communication between IVPS and NB LTs usesXLES protocol.

IVPS card is located into a hub node From the voice service point of view, one IVPS can control several ISAM-V

cascading nodes (up to 4 levels) with a number of NB LT cards as well as severalISAM-V distributed nodes (i.e. accessible via a common EMAN) with a numberof NB LT cards

All User Port in one NB LT are controlled from the same IVPS

Note: Although it is not a system constraint, the network deployment should beplanned so that all user ports in one shelf are associated to/ controlled by only oneIVPS. This is recommended for two different reasons:

simplest network architecture with an easier operation to keep compatibility with further features in order to limit the bandwidth/number

of calls per shelf

The different traffic flows related to voice service are isolated into differentVLANs which are defined over the EMAN and in the ISAM SHub:

Voice VLAN:RTP traffic and XLES signaling is carried over this VLAN

MEGACO VLAN:for MEGACO signaling traffic between CS and the media GW and

SIGTRAN signaling between ASP and the signalling GW External OAM VLAN:

for provider operation and management

Both hub and subtending (cascading or remote (distributed)) configurations arepossible. In cascading configurations, the connection to the hub is via Fast orGigabit Ethernet (optical or electrical) to the SHub of the hub node.

1 System Overview



IVPS

The IVPS communicates with the voice line boards by means of an extendedBLES (XLES) proprietary protocol. The IVPS terminates the proprietary signalingmessages from the voice boards, provides a MEGACO interface with the call serverand handles the specific OAM needed to support VoIP service.

The IVPS functions are:

The signaling interface with the call server or soft-switch (MEGACO signaling) Internal proprietary protocol (XLES) for signaling supervision and control with

POLT line termination boards Digit Map processing (either under Megaco reception or by CDE data) Specific OAM interface needed to support VoIP configuration and service Persistent storage of the voice service database including back-up and restore Regarding ISDN signaling:

IVPS performs message relay between the DSS1 XLES messages containing Q921and the IUA over SCTP messages that carry the Q931 info towards the ASP.

IVPS relies the ISDN signalling packets (DSS1) from/to UDP-XLES socket andtranslates those related to Q921 info (SAPI, TEI) to/from IUA/SCTP.

Q931 layer is not processed by IVPS or BALT, but transparently sent/received asSIGTRAN packets information to/from the Call Server.

Configuration data:IVPS stores the L1 activation type (per-call or permanent) for each port.When the communication with a BALT is established, IVPS sends thisinformation to BALT.

POLT

The POLT supports up to 48 POTS interfaces and integrates functions such asringing, digit detection and tone generation. The POLT provides a classical POTSinterface towards the subscriber and performs the packetization of the voice over

RTP, sending the voice directly to the network as VoIP over Ethernet.

This is the analogue Z interface connecting to a telephone set. The main commonfeatures are the following:

Interfacing at subscribers side according to the POTS analogue Z interface: Line feeding Symmetrical programmable ringing Polarity reversal Programmable line impedance with echo cancellation Overvoltage protection

Signaling events processing and communication with IVPS according to internalXLES protocol

DTMF/pulse detection/processing Caller identification services (FSK, DTMF, on-off hook) Tone generation towards subscriber side Howler tone generation Tone generation towards network side (needed for ring-back tone) Metering pulses generation


24/112

1 System Overview



Ringing generation. Integrated line testing Coding (G.711 and either G.729 or G.723.1) and packetizing voice in RTP and

directly forwarding to/from packet network based on MAC/IP/UDP addresses Voice activity detection, comfort noise, packet loss concealment

Near end echo cancellation Fax/modem detection/bypass Support of relay of DTMF and some fax/modem tones by means of RFC 2833

BALT

The interface of the BALT corresponds to the U reference point of the DigitalTransmission System as defined in G.961.

The interface provides full-duplex and bit independent transmission via two wires ata net bit rate of 144 Kbit/s, a transparent 1 Kbit/s service channel and a 1 Kbit/smaintenance channel for loops and error messages on subscriber lines, plussynchronization bits.

Duplex transmission is achieved through the use of Echo Cancellation Hybrid. Withthe Echo Cancellation Hybrid method the Echo Canceller (EC) produces a replica ofthe echo of the transmitted signal that is subtracted from the total received signal. Theecho is the result of imperfect balance of the hybrid and impedance discontinuitiesin the line.

The 2B1Q encoding is applied; the symbol rate on the line is therefore 80 KBaud.

In the case of ISDN BA over IP, the functionality is split between the BALT lineboard and the IVPS board. The BALT board supports 24 ISDN BA user ports andterminates Q.921 data links; IVPS establishes a SIGTRAN communication with theASP. ASP is responsible for terminating IUA/SCTP and processing the Q.931messages.

The BALT functions are:

Line Termination for the U interface of ISDN Basic Access ITU G.961 G.711 (A,), G.729a/b, G.723.1 coding Local Echo cancellation (G.168, G.165, none) 16 ms. tail length Voice activity detection, comfort noise, packet loss concealment Configurable jitter buffer: adaptive or fixed size (per call) Automatic fax/modem detection and bypass (transparent fax and modem service) Enhanced end-to-end tone detection and generation (as per RFC 2833) Call progress tone generation: Dial Tone, Special (Information) Dial Tone, Ring

Back Tone, Congestion Tone, Busy Tone

1 System Overview



DTMF digit detection: when a call is in stable phase and the user sends DTMFdigits to, for example, an automatic Call Centre, the BALT must detect theDTMF.

Support for duplication of RTP streams for future Lawful Interceptionimplementation

Regarding ISDN signaling: Termination of Q921 protocol (SABME,UA, RR,..., timers, states,...) BALT establishes, releases and maintains data links with TEs as specified in Q.921.

For this, BALT controls LAPD sequence numbers, maintain Q.921 state machines,etc. There is one established data link for each TEI.

There is one data link established between BALT and IVPS. XLES for POTS istransported inside that data link.

Dynamic TEI assignment is done by BALT The ASP (through IVPS) may command the removal of a particular TEI. BALT

carries out this action and notifies it to IVPS. Also, ASP may ask for TEI status.

Integrated Line Testing

The integrated Line Testing functionality can be used by the operator in order todetect failure conditions and anticipate possible problems.

Note:Only line testing of POTS line terminations can be tested.

Tests can be performed on demand (required by an operator command).

The following test can be performed:

Electrical measurement test:The purpose of these tests is the measurement of electrical parameters. These testsdo not require customer assistance. Any or all of these tests can be invoked in thesame test request for a given user port. Electrical measurement tests are:

Foreign voltage (AC/DC): This test is measuring foreign voltage between wires. Capacitance: This test is measuring capacitance between wires. Insulating resistance: This test is measuring insulating resistance between wires. Impedance: This test is measuring the impedance between wires. Termination (M Socket detection): This test is to detect whether a phone or just a

resistance connects the line.

Feeding voltage: This test is performed measuring voltage over wires in open circuitand verifying voltage remains within thresholds.

Feeding current: This test is performed connecting a resistor loading the wires andmeasuring the current in limiting mode.

Noise level: This test is to detect abnormal noise level, e.g. crosstalk


26/112

1 System Overview



Group test:This test consists of a combination of predefined electrical measurementsrequested by the OS as previous electrical measurement tests. It includes acombination of voltage, capacitance and insulating resistance measurements. Itcan be performed on ISAM-V devices in 10 s. Thirteen possible measurements

are: AC Foreign voltage: a/Earth, b/Earth and a/b DC Foreign voltage: a/Earth, b/Earth and a/b Capacitance: a/Earth with b grounded, b/Earth with a grounded and a/b Insulation resistance: a/Earth with b grounded, b/Earth with a grounded, a/b and b/a

Dial tone test:This test checks the ability of the line circuit to detect an off-hook and to checkthe provision of the dial tone from the MGC.

An off-hook condition is simulated in the NE. This off-hook must be detected bythe line circuit and is further processed by call-handling software; the MGC willthen interpret it as a real off-hook and will send a dial tone. The time is measuredand compared with a predefined threshold. Returned result is the delay to dial

tone. Howler tone test

This test lets the user know that the mike is not hooked on correctly and restoresthe user state from parking to idle after the user hooks on the mike. If the user doesnot hook on the mike, the howler tone is stopped after a predefined timeout. Thehowler tone level and frequency depend on different countries specifications.

Status monitor

This test lets the operator know the indicated users status.

2.2 7302 ISAM System Initialization

GeneralThis section describes the initialization of the 7302 ISAM.

After the SHub subsystem and the LT shelf subsystem are powered up, the bootsequence starts for each subsystem.

SHub Subsystem Initialization

While booting, the SHub subsystem retrieves all necessary parameters from memoryor from pre-configured defaults. A pre-defined OAM VLAN with VLAN ID(IC-VLAN= 4094) is fixed and cannot be used in the connected network because thevalue 4094 is reserved and may not be used externally. This internal OAM VLAN isalso pre-defined in the NT-LT initialisation. This VLAN is used for the software

download to the LTs and the configuration of the LTs.

If a configuration database was saved, and the SHub subsystem was set to restore thisconfiguration before the last system down, the SHub subsystem will retrieve thisconfiguration.

The SHub subsystem is now operational.

For more information, refer to the Operations and Maintenance Using CLI.

LT Shelf Subsystem Initialization

Since the NT board is the system manager, it has the control over the system initphases of the LT shelf subsystem and is responsible for the sequencing of theinitialization phases of the NT board and the rest of the 7302 ISAM. This is incontrast to the SHub subsystem which is initialized independently. The initializationof the LTs and the SHub subsystem happen parallel. However as long as the SHubsubsystem is not up, the NT will not establish communication with the LTs. The NTsoftware can check if the SHub subsystem is alive.

The LT shelf subsystem initialization consists of the following phases:

Local NT initialization System initialization Enable external 7302 ISAM management

Local NT Initialization

The following phases are identified for the local NT initialization:

Boot phase Overall SoftWare (OSW) startup Initialization phase Restore data from non-volatile memory

In this phase the LT boards boot and wait for the NT board to get their OSW.


33/112




System Initialization

In the first phase of the system initialization, the NT board detects the LT boards, theACU and the appliques (HW) and downloads the appropriate SW to the LT boards.

The LT boards start up with their SW and perform their specific initialisations.

After these initialisations, each LIM board sends a signal to the NT board. Thesecond phase of the system initialization begins when the NT board receives thissignal. Now the NT board configures each LT board.

Enable External 7302 ISAM Management

When the LT boards are configured, the 7302 ISAM management is enabled on theNT board and the 7302 ISAM indicates that the initialization is fully complete andthe system is operational.

Note:For more information about the initialization and startup of the 7302 ISAMplease refer to the Operations and Maintenance Using CLI.


34/112




2.3 Network Management

Figure 2-2shows how the 7302 ISAM can be managed in a network.

Figure 2-2 7302 ISAM Network Management

The remote Craft Terminal (CT) uses TL1 commands or Command Line Interface(CLI) commands. TL1 is used for pre-provisioning of the NT board. CLI is used tomanage both the SHub subsystem as the NT board.

Figure 2-3shows the management topology for the two subsystems of the7302 ISAM.

Figure 2-3 7302 ISAM Management Topology

Note:If the 7302 ISAM is configured to have only one public IP address, then thedirect SNMP management interface to the SHub is no longer available. The SHubwill then be managed through the SNMP interface of the NT.

The NT Controller and the SHub subsystem each contain a separate SNMP agent.The NT Controller / LIMs and the SHub subsystem can be managed via an EMS.

It is also possible to use local TL1 or CLI craft terminal on the NT board to managethe LTs.

An integrated CLI approach is implemented on the NT board using an CLI agent.This agent implements CLI commands for the NT Controller / LIMs and the SHubsubsystem. However, there is no semantical integration.

Table 2-1shows an overview of the managers which are involved:

Table 2-1 Manager Overview

Note: External OAM VLAN

The SHub subsystem supports inband management. This happens through adedicated VLAN, which must be configured (if different than 4043) on both theSHub subsystem as on the NT.
