We are going to add a PRI between the Option 11c and another pbx. We have asked for a quote for a TDMI card and D-channel daughterboard. The vendor tells us that since we are at Call Server VERSION 2121 RELEASE 3 ISSUE 00, we don't need D-channel hardware. It's now covered in the s/w - System Limits excerpt: DCH 80 LEFT 79 USED 1 TMDI D-CHANNELS 64 LEFT 63 USED 1
True? No hardware required for a D-channel??
thanks,
True
If you've got a TMDI card, and at least one TMDI D-Channel ISM available (you do, according to the posted info!), then you just program the hardware that is already present on the TMDI card. It looks like you've already got a TMDI D-Channel, and a regular D-Channel programmed in the switch. It programs as a MSDL. Card x (the slot the TMDI lives in), port 0.
On another note: Assuming you've already got a T1 going somewhere else, you won't need a clock controller either. If the other switch has no T1's going anywhere, it will need a clock controller, and you will want to slave it off of this carrier. If it also already has a T1 going to some sort of Public switch - Telco, MCI, etc. - and the switch you are at now does the same, you are already all set for timing.
