AS 5300 RAS solutions PRI vs a Digital Trunk


So I'm down here with a customer trying to figure out how to configure this AS5300 to work with a DIGITAL Trunk for channelized bank comming in to a 48 port mica internal modems.

I'm use to seeing these using a PRI setup but need to know how if possible to setup my interface for a digital trunk. Any help appreciated.

Channel Associated Signaling (CAS) is also referred to as Robbed Bit Signaling. In this type of signaling, the least significant bit of information in a T1 signal is "robbed" from the channels that carry voice and is used to transmit framing and clocking information. This is sometimes called "in-band" signaling. CAS is a method of signaling each traffic channel rather than having a dedicated signaling channel (like ISDN). In other words, the signaling for a particular traffic circuit is permanently associated with that circuit. The most common forms of CAS signaling are loopstart, groundstart, Equal Access North American (EANA), and E&M. In addition to receiving and placing calls, CAS signaling also processes the receipt of Dialed Number Identification Service (DNIS) and automatic number identification (ANI) information, which is used to support authentication and other functions.
