Option 11 E&M Trunk Card
Configuration Example

Introduction

The following example shows how to configure a Nortel PBX Option 11 E&M Trunk Card, eg: NT8D15, to connect to a Cisco E&M voice port.

Hardware and Software Versions

To implement this configuration, you need the following:

• Nortel PBX Option 11
• Software Release 23 or later
• Nortel E&M Trunk Card, eg: NT8D15

Circuit types:

E&M trunks may be type 1 or type 2, two-wire or four-wire, immediate, wink, or delay dial start.

• EMTY TY1/TY2 - type 1 or 2
• SIGL EAM/EM4 - 2 or 4-wire
• STRI IMM/WNK/DDL - immediate, wink, or delay dial

Cross-connect:

A 25 pair line card cable is presented on BIX as follows, with 4 pairs per trunk interface:

Notes:

• TX/RX=Voice pairs; E=Ear, M=Mouth, B=Signal Battery, G=Signal Ground
• 4-wire circuits use TX and RX pairs, 2-wire circuits use TX only (2-way)
• type 1 circuits use E&M signaling, type 2 circuits use E&M plus B&G

Configuration:

Building route data block. Use double digits w/ route data block:

LD 16

REQ: new
TYPE: rdb              Route Data Block
CUST: 0
DMOD:
ROUT: 21               Route Number
TKTP: tie
ESN:       
                       Hit RETURN until ICOG prompt
ICOG: iao              Incoming, Outgoing

ACOD: 71
TARG: 0                TGAR 0 and ENDCOST 0
BILN:
                       Hit RETURN until CNTL prompt
CNTL: yes
TIMR:
SST:
NEDC: eth              NEAR END DISCONNECT set for EITHER
FEDC: eth              FAR END DISCONNECT set for EITHER
CPDC:
                       Hit RETURN until ALRM prompt

LD21                   Load 21 to VIEW/PRINT RDB

REQ: prt
TYPE: rdb
CUST: 0
ROUT: 21

The trunk configuration must match the circuit type.

Load 14 to add new trunk:

LD 14

REQ: NEW
TYPE: TIE
TN: 9 0                Analog starts at 0, Digital starts at 1
XTRK: XEM
CUST: 0
NCOS: 0
RTMB: 21 1
MNDN:
TGAR: 0

STRI: IMM
STR0: IMM
SUPN:

View (print) trunk:

LD 20

REQ: PRT
TYPE: TRK
TN: 9 0
RTMB:                All returns until the end
****

After finishing all 4 trunks, you must enable the card/trunks:

LD 32

STAT 9
DISC 9               Disable card 9:The E&M CARD
ENLC 9               Enable card 9
****

To modify E&M type, operation (2 or 4-wires), and/or signaling:

LD 14

REQ: CHG              Change trunk configuration
TN: 9 0               Analog starts at 0, Digital starts at 1
XTRK: XEM
CUST: 0
NCOS: 0
RTMB: 21 1
MNDN:
TGAR: 0
SIGL: EM4             EM4 for 4-wires, EAM for 2-wire
EMTY: TY2             E&M Type 2 (depends on cabling)
