Problem with PRI Drop-and-Insert

manyakinanton · ‎07-22-2009

Hello,

We use 2 PABX connected to each other via PRI. Config 2811(please see attached the file) is set between. We have attempted to send PRI via 2811 using Drop-and-Insert. Diagnostic commands do not show any error messages however PABX do not "see" each other.

Could you please give your kind comments how to solve the issue or address me to the right contact.

your prompt response will be highly

Hello Anton,

E1 D channel should be 15 not 16

I think you need to cross-connect timeslot 15 not 16

Hope to help

Hello Anton,

I've confused the cisco indexes for interfaces that starts with 0.

timeslot 16 should be fine.

there are additional options for the commands like

tdm-group

tdm-group-no

timeslots timeslot-list type [e&m | fxs

[loop-start |

ground-start] fxo [loop-start |

ground-start]

see

but I don't think this applies to you.

Sorry for the confusion

Hope to help

Giuseppe
