P-Phone Services

The Access Navigator / GR-303 Host with P-Phone includes Nortel Proprietary Phone (P-Phone) Centrex service support using remote Adit 600 terminals with P-Phone service cards. The cards convert the customer’s analog P-Phone signals to more efficient digital loop carriers. These digital signals that are then transmitted over DS0s on the Access Navigator’s drop DS1.

Command and signaling information for all P-Phones is carried by message packets sent over the IP DS0 management channel between the Access Navigator and remote Adit 600, then over the GR-303 EOC channel between the Access Navigator and the Nortel DMS switch. The Access Navigator can support up to 384 P-Phone channels originating from up to 14 remote Adit 600s. For a detailed description of supported P-Phone features, see the Adit 600 User Manual.
