T1 and E1 CAS Configuration

Lets configure T1 CAS connection

First let's configure digital interface such as E1 and T1

network-clock-participate wic 1  ---->>> configure module to participate in clocking
network-clock-select 1 T1 0/1/0  ---->>> select clocking interface

isdn swith-type primary-net5 ---->>> select clocking interface define in global config mode, which ISDN switch type to use - TSP always provide this info

Netx, lets configure controller

controller T1 0/1/0 ---->>> conftroller configuration
framing esf ---->>> framing type configuration: "superframe" - concatenat  12 frames and "extanded superframe" with 24 frames. Framing type - how router determines frames
linecode b8zs ---->>> linecondig b8zs or ami. Linecode type - how bits are put into wire
ds0-group 0 timeslots 1-6 type e&m-fgd ---->>> use first 6 channels and e&m-fgd to receive inbound calls and receive ANI
ds0-group 1 timeslots 7-12 type fgd-eana ---->>> use next 6 channels and fgd-eana to send outbound calls and send ANI

Because T1 CAS doesn't have signalling channel it's limited by default to send some supplementary information such ANI, etc and we should configure several special types of ds0-groups

voice-port 0/1/0:0 ---->>> voice ports which was created, after we've initiated command ds0-group 0 and 1
voice-port 0/1/0:1 ---->>> voice ports which was created, after we've initiated command ds0-group 0 and 1

dial-peer voice 1000 pots --->>> inbound dial-peer
incoming called-number .
direct-inward-dial
port 0/1/0:0
dial-peer voice 2000 pots --->>> outbound dial-peer
destination-pattern 8T
port 0/1/0:1
