Troubleshooting a Network Connection Problem

6-27

If it is, conﬁgure the DCE for DSR to follow CD, or conﬁgure DSR to be in

the off state until the DCE receives a DTR signal, and reconnect the CSUs.

Unfortunately, DCE manufacturers use inconsistent terminology for these

settings.

The V.35 pin assignments are

• RLSD (received line signal detect) Pin F

• RI (ring indicator) Pin J

• DSR (data set ready) Pin E

• DTR (data terminal ready) Pin H

Troubleshooting ISDN BRI and PRI

Troubleshoot ISDN BRI and PRI as follows:

1. (ISDN PRI only) Verify that MCT1/MCE1 initialized correctly.

Example

# 7: mm/dd/yy 10:38:39.363 DEBUG SLOT 4 DS1E1 Code: 50

Connector COM1, Logical Line 1 time_slot = 16.

Connector COM1, Logical Line 1 time_slot = 17.

Connector COM1, Logical Line 1 time_slot = 18.

Connector COM1, Logical Line 1 time_slot = 19.

Connector COM1, Logical Line 1 time_slot = 20.

Connector COM1, Logical Line 1 time_slot = 21.

Connector COM1, Logical Line 1 time_slot = 22.

Connector COM1, Logical Line 1 time_slot = 23.

Connector COM1, Logical Line 1 time_slot = 24.

Connector COM1, Logical Line 1 initialization complete

2. Filter the log to display messages of all severity levels for the ISDN, ISDN

BRI, and switched access services running on the slots in question.

The Technician Interface command is

log -fftwid -eISDN -eISDN_BRI -eSWSERV -s

<slot_no.>

Note: This is the preferred way to resolve this problem. However, if the CSUs

do not support this solution, use the Conﬁguration Manager to edit the

connector of the backup line, click on modem, and disable the ring indicator.

DTR then goes high only if the primary line becomes unavailable.
