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 .
