Hi,
Im triying to configure a E1 with the PRI group timeslots command as follow:
controller E1 0/0/0
line-termination 75-ohm
pri-group timeslots 1-30
Then, I'm using interface serial0/0/0:15 to configure signalling.
Right know everything is working fine, but I'm a little confused.
As fas as I know, E1 have 32 timeslots or channels (1 to 32), where the fisrt channel is TS0 and the last one is TS31. Signalling should always go on channel 16, which is TS15.
My question is, in the controller configuration, shouldnt be "pri-group timeslots 1-31" instead of 1-30? ...
If I have pri-group timeslots 1-30 does it means that I only configured 29 voice channels? because TS15 is not going to be usefull
When I do a show voice port summary, I still see 30 channels =S
IN OUT
PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC
