2.1.2.3 Radio Port Interface Module
Each RPC controls and feeds a maximum of 32 RPs. The RPC connects to the
RPs through a 2-wire proprietary interface. Line power feeding from the RPC
provides a power source of 116V DC to the RPs.
The RPC controls the RPs via 8 RPIF modules. Each RPIF module provides an
ISDN Basic Rate interface to 4 RPs. The RP is extended from the RPC to a
maximum distance of 5.0km using a pair of φ0.5 wires and approximately 3.5 km
using a pair of φ0.4 wires.
The Radio Port Interface (RPIF) module communicates externally with four RPs
through ISDN Basic Rate Interfaces (BRI). In addition, it communicates
