Hi. We had a R2 signaling configuration, in which we used ds0-groups to specify the use of only some timeslots, like this:
controller E1 1
framing NO-CRC4
ds0-group 2 timeslots 1-2 type r2-digital r2-compelled ani
ds0-group 3 timeslots 3-15,17-19 type r2-digital r2-compelled ani
ds0-group 4 timeslots 20-23,30-31 type r2-digital r2-compelled ani
cas-custom 2
We migrated to SS7 signaling (AS5400 with PGW). We used pri-groups and it's working OK. But now we need to specify the use of only some timeslots per customer (kinda like the R2 config above), but with pri-groups we can't do this. I think the solution will be using trunk-groups, maybe like the following:
trunk group CUSTOMER1
description B Channels reserved for Emergency Calls
!
controller E1 6/0
framing NO-CRC4
pri-group timeslots 1-31 nfas_d primary nfas_int 0 nfas_group 0
trunk-group CUSTOMER1 timeslots 1-2
trunk-group CUSTOMER2 timeslots 20-31
!
controller E1 6/1
framing NO-CRC4
pri-group timeslots 1-31 nfas_d none nfas_int 1 nfas_group 0
!
interface Serial6/0
no ip address
!
interface Serial6/0:15
no ip address
encapsulation hdlc
isdn switch-type primary-ni2c
isdn incoming-voice modem
isdn rlm-group 1
no isdn send-status-enquiry
isdn negotiate-bchan resend-setup
!
voice-port 6/0:D
!
!
!
dial-peer voice 7099 voip
destination-pattern xxxxx
progress_ind setup enable 3
voice-class codec 1
session target ipv4:xxxxx
!
dial-peer voice 9999 pots
trunkgroup CUSTOMER1
huntstop
destination-pattern xxxxx
progress_ind setup enable 3
direct-inward-dial
port 6/0:D
!
Would this work? Do we have to change something in the PGW in order to make this config work? Any help would be very appreciated.
