6.4 Troubleshooting

The following table presents the event types as they appear on the Event Log File

and lists the actions required to correct the event (alarm) indication.

Table 6-4. IPmux-11 Troubleshooting Chart

Fault Probable Cause Remedial Action

E1/T1 equipment

connected to IPmux-11 is

not synchronized with

IPmux-11.

Configuration or physical layer

problems

1. Check cables and physical

connectivity.

2. Check IPmux-11 E1/T1

configuration and, if necessary,

other IPmux-11 parameters.

3. Check E1/T1 physical connection

(use loopbacks).

Slips and errors in E1/T1

equipment

• Ethernet port in switch and

IPmux-11 are not in the same

rate or duplex mode

• Ethernet port is set to work in

half duplex mode (may cause

extreme PDV because of

collisions and backoffs)

• Timing configuration is not

properly set (periodic buffer

under/overflows shown on IP

channel status menu)

• Network PDV or lost frames

1. Check E1/T1 physical connection

(use loopbacks).

2. Check timing settings according to

explanation in this manual.

3. Check switch and IPmux-11 port

configuration (negotiation, rate,

duplex mode).

4. Check PDV introduced by the

network, and, if necessary, increase

PDVT jitter buffer setting..

Echo in voice High delay in voice path 1. Check network delay and try to

decrease it.

2. Try to decrease PDVT (jitter) buffer.
