Chapter 1 Introduction

PRODUCT OVERVIEW

The MX2800 is an M13 mu ltiplexer that consolidates T1 and E1

signals into a T3 circuit. This unit p rovid es a cost-effective, versa tile

tool for combining indep end ent T1s, E1s, or a combinat ion of the

two over th e same T3 circuit.

The MX2800 hou ses two hot-swap pab le controller cards w hich

provid e 1:1 redun dancy for the T1 and T3 signals as well as the T3

connections.

Embedded SNMP (simple network m anagement p rotocol) and

Telnet are available throu gh the mod em p ort using SLIP/ PPP orthrou gh th e 10BaseT ethernet p ort. Using th e Managem ent

Information Base II (MIB II), RFC 1407 standard s, and an ADTRAN

enterprise MIB, the MX2800 can be configured , monitored , and

diagnosed with standard SNMP network man agement programs

such as H ewlett Packards H P OpenView and Cabletrons

Spectrum.

Comp lete configuration, diagnostics, and performance monitoring

are available through SNMP, Telnet, or a VT 100 terminal interface.

This connection can be m ad e via ethernet , a local EIA-232 link, or

throu gh the bu ilt-in V.34 modem (see the no te at the end of this

section on page 1-2). The mod em can d ial-out a cry for help for

un its located in u nm ann ed facilities. The MX2800 is d esigned for

either d esktop use or for installation in a 19- or 23-inch rack.

T3 OVERVIEW

A T3 provid es the sam e bandwidth as 28 T1s. Typ ically, leasing a T3line costs the sam e as eight to ten T1s. Using the MX2800, a single

T3 can p rovide intern et connectivity and voice (local and long

d istance) to individu al sites across up to 28 ind ividu al DSX-1s. T3 is

also extremely cost effective for backhau ling local and lon g

distance voice.

SNMP

The MX2800's embed ded SNMP feature allows the u nit to be

accessed and controlled by a netw ork man ager through the

10BaseT local area network (LAN) port. The MX2800 supports th e

MIB-II stand ard , RFC 1213, and the ADTRAN Enterprise Specific

MIB.

The term SNMP broad ly refers to the message p rotocols used to

exchange information between the network man agement system(NMS) and the managed devices, as well as to the structure of

device management databases. SNMP has three basic compon ents,

the netw ork manager, the agent, and the MIB.

Network ManagerThe network manager is a set of control program s that collect,

control, and present d ata pertinent to the operation of the netw ork

devices. These programs reside on a network m anagem ent station.

AgentThe agent is a control program that resides in every network

device. This program respond s to queries and comm and s from the

network man ager, returns requested information or invokes

configuration changes initiated by the manager, and sends

un solicited trap s to the manager.

MIB files are available from ADTRA N in the support section of the

ADTRAN Web page atwww.adtran.com.

to perform initial wiring and to connect and disconnect DC pow er

wh en replacing rackmou nt u nits.

To establish DC p ower, use 12 to 26 AWG wire to connect the

mod ular connector as follows:

1. Connect the wire lugs on the mod ular connector which

correspon d to the p ositive (RET) and negative (-) terminals on

the rear p anel to a -48V DC, 1A sou rce.

2. Connect the wire lug on the mod ular connector whichcorresponds to th e PWR FAIL terminal on the rear pan el to a

battery backup source.

3. Connect the remaining wire lug to the frame groun d .

Once the mod ular connector is wired, pu sh it firmly into one of the

rear panel POWER connectors. Figure 2-1 an d Table 2-1 on page 2-3

illustrate the DC pow er connector and give definitions for the fourconnector symbols.

The ADTRAN MX2800 MIB is available in the support section of the

2-4 MX2800 User Manual 61200290L1-1

The following UL requirements mu st be met du ring installation of

the MX2800 DC version:

1. The un it mu st be connected to a reliably groun ded -48 VDC

source which is electrically isolated from the AC source.

2. The branch circuit overcur rent protection shou ld be a fuse or

circuit breaker rated -48 V, 15 A.

3. The un it shou ld be installed in accordance with the

requ iremen ts of NEC NFPA 70.

4. A read ily-accessible d isconnect device tha t is suitablyapp roved and rated should be incorporated in the fixed w iring.

RACKMOUNT INSTALLATION

The MX2800 can be mounted into a stan dard 19- or 23-inch

equip ment rack. (SeeEstablishing Terminal Connection on p age 2-10

for information on termina l configuration.) Follow these steps to

mou nt your u nit into a rack:

1. Prepare the MX2800 mou nting ears by scraping the pa int away

from the m ounting ears portion that makes contact w ith the

rack and the portion w here the screw m ounts into the side of

the MX2800.

Use copper conductors only.

To ensure proper grounding in 23-inch rack configurations, prepare the

MX2800s mounting ears for installation by scraping away thepaint .Scraping away the paint exposes the bare metal, allowing the

MX2800 to make proper contact with the rack.



25/142


61200290L1-1 MX2800 User Manual 2-5

2. Install the mou nt ing flanges on each side of the MX2800 at one

of the three ava ilable positions.

3. After the flanges have been installed, position the MX2800 at

the correct location with in the rack and secure the m oun ting

flanges to th e mou nting r ails of the rack.

4. Make all netw ork, DTE, and p ower connections to the rear of

the un it. See Power Up on p age 2-2 for more inform ation on

making th e DC p ower connection.

5. Using the 8-position modu lar to DB-9 female connector and the

8-position m odular to 8-position m odu lar cable, connect a

VT 100 terminal device to the CRAFT port on th e front pan el ofthe unit.

Connecting the Breakout Panel

The optional breakou t p anel (P/ N 1200291L1) connects to the

MX2800 via the IN an d OUT Cham p connectors and provid es 28 RJ

connectors for the ind ividual T1s/ E1s. Shipm ent includ es two six-foot, 64-pin to 64-pin Am p cables w hich allow d irect cabling to the

MX2800. Connect the breakou t panels IN Champ connector to the

MX2800s IN Champ connector an d the breakout p anels OUT

Champ connector to the MX2800s OUT Cham p connector (see

Figure 2-2).

Be sure to install the flanges with the screws provided.

Two MX2800s may be stacked with no spacing between units. ADTRA N

recommends 1U (1.75") of separation above and below the two stacked

units. This spacing allows the unit to dissipate heat. The design of the

MX2800 uses the chassis to distribute heat generated by the unit' s

internal cards. This design allows the unit to operate without a cooling

fan, which increases the overall reliability of the un it.

in M12 (four T1s) or G.747 (three E1s) format. When set to M12(4XT1), the four T1s for the selected group are fram ed p er AN SIT1.107. When set to G.747 (3XE1), the first three T1/ E1 por ts of the

selected group are framed per CCITT G.747 into the DS3 stream.

The fourth T1/ E1 por t of the selected grou p is not ava ilable in this

mod e. Any combination ofM12 (4XT1) an d G.747 (3XE1) isallowed.

T1/E1 INTERFACE

The T1/E1 INTERFACEmenu (show n in Figure 3-4) allows you to

activate/ deactivate individual T1s and E1s and to set their line

coding, length, loopback detection, circuit p rotection, and line ID

string. The T1/ E1 code violation th reshold is also configured

throu gh th is menu . Configuration selections are described in the

sections following Figure 3-4.

Set Multiple

Use SET MULTIPLE (see Figure 3-6) to enable or d isable any or all ofthe T1/ E1s at one time. To enable or d isable all T1/ E1s, set FIRST to

1 and LAST to 28. Enter APPLYSETTINGS before leaving th e m enu . Toenable or d isable only some of the T1/ E1s, set FIRST an d LAST to

correspon d to th e lines you want to enable or disable. Enter APPLY

SETTINGS. You can n ow either leave the menu or continue to en ternew FIRST an d LAST nu mbers for other lines. Remember to app ly

the settings wh en you finish each setting.

A DS2 can be divided into either three E1s or four T1s. Therefore, when

dealing with an E1 configuration, some of the fields in the T1/E1 INTER-

FACEmenus do not apply (and therefore display N/A).

Choose which T1/ E1 lines to p rotect (see Figure 3-10). If a T1/ E1 isset to DISABLED, then the failure of that one line will not cause th econtroller cards to switch. If set to ENABLED, then the lines failure

couldcause the cards to switch (dep ending on the PROTECTION

THRESHOLD setting in this men u).

The PROTECTION THRESHOLD setting determines how man y of theENABLED lines m ust fail before a card sw itch occurs. If you w ant the
