a) E & M card with 2713 Hz Loop back – Module# 811760:
This feature will provide digital loop back (both audio and signaling) when activated by a 2713 Hz tone of specified level and duration. The requirements are provided by BellCore PUB 42004. When a validated tone is detected the channel should disconnect the user and provide loop back of signals (audio and signaling) received from the network. The loop back must be performed without inserting any gain or loss in the path. After tone activation, the channel shall remain in the loop back mode unless deactivated for a period of 20 minutes (+/- 1 minute) after which the channel shall automatically revert to the idle (non loop back) mode.
b)(Optional) P-Phone Line card with 8 ports (PPS Module# 812160 and PPO Module# 813160):
The purpose of this feature is to provide an 8-port P-Phone Line card in the Streamline for Host 1.2. The P-Phone line card is used by Nortel to support transport of P-Phone service. There are two applications of the line card, one at the Office end (P-Phone Office – PPO), and one at the Station end (P-Phone Station – PPS). Hence, PPO and PPS are two user cards designed to support connectivity between a Nortel SL-100 PBX or DMS-100 based Centrex PBX and Nortel M5000 series Electronic Business Sets (P-Phones). The P-Phone is an electronic telephone set capable of supporting premium Meridian Digital Centrex (MDC) features offered by the local DMS switch. The data channel allows out-of-band signaling between the P-Phone and the DMS switch. This data channel allows the user to activate MDC features, such as conference calling by simply pushing keys on the P-Phone set, and for the DMS to deliver information, such as caller identification, to the P-Phone display. This P-Phone line card encodes the received out-of-band signaling tones, transports them across the carrier and decodes the digital representation back to out-of-band tones at the other end. Hence, this line card simply repeats the signaling end-to-end.
The market for P-Phones is by definition limited to Nortel switches and PBXs: DMS100 (Class 5 switch), DMS500 (Combination of Class 5 and a Tandem switch), DMS10 (Lower capacity switch for rural areas) and SL100 (Large Enterprise PBX).
P-Phones supported include: M5000 series business sets, models M5009, M5112, M5209, M5212 and M5312.
