T1/E1 Drop & Insert (D&I) NIM

The XSR’s 2-port T1/E1 D&I NIM card, as shown in Figure A-25, is designed as an intermediary between the Central Office T1/E1 line and a PBX. It de-couples Channel Associated Signaling (CAS) and Voice DS0 timeslots and redirects them to a PBX, and conversely, reintegrates Voice DS0 timeslots from the PBX with the T1/E1 data stream. Both ports are functionally equivalent.

Figure A-25 T1/E1 D&I NIM Card

The T1/E1 D&I NIM provides long- and short-haul capabilities and Drop and Insert functionality via a fully configurable Time Division Multiplexed (TDM) switch. It can be configured for data only, or voice/data applications. In Data-Only mode, both ports pass data, whereas in Voice/Data mode, one port passes a voice/data stream, while the other passes only voice.

The T1/E1 D&I NIM maintains high reliability of voice traffic by using a bypass relay to ensure continued service even if a power failure occurs or the NIM enters an abnormal state. In such an event, the two ports are connected, bypassing the NIM, thus allowing uninterrupted bidirectional voice transmission. To ensure service, remember to configure voice timeslots on both sides of the connection in the same manner. That is, if timeslots 3-5 are configured for voice on the NIM, the same DS0s should be configured for voice at the Central Office. Refer to the XSR User’s Guide for instructions.
