Dear All,
I trying to setup a PRI to PRI connection from 908e to 7100
Currently I am getting an error:
On 908e I have:
interface t1 0/2
description PRI Handoff to 7100

no shutdown
interface pri 3

!
On 7100 I have:

trunk T05
The error I am getting is:
ISDN.EP | PRI 1 D channel is DOWN |
Its nonstop.....I tried different cables and it still fails.
If anyone can help I would be very grateful.
Warm Regards,
Vi
On the 908e (or any 9XXe) gen 1 and gen 2, only T1 ports 3 and 4 can be used to terminate PRI or CAS. T1 0/1 and 0/2 are for data only. There's a subtle hint about this printed next to the connectors themselves.
Try:
interface t1 0/2
description unused
shutdown
interface t1 0/3
description PRI Handoff to 7100
tdm-group 3 timeslots 1-24 speed 64
no shutdown
interface pri 3
description pri 3
no connect t1 0/2 tdm-group 3
connect t1 0/3 tdm-group 3
role network b-channel-restarts enable
no shutdown
Then move the cable from T1 0/2 to t1 0/3.
You will probably need a T1 crossover cable between the TA908e and the 7100. This is different from an Ethernet crossover and you'll likely have to wire it yourself. If the T1 itself is down (red light on TA908e) then try a crossover cable.

Pins 3, 6, 7,and 8 can be omitted or wired straight, they're not used.

Ok that explains it. If I use t 0/3 it works fine. Thank you very much for help.
