RPC Installation 2 2 RPC Installation 2.1 General Description The Radio Port Controller (RPC) functions as the controller and power distributor for the Radio Ports (RPs). It is also the concentrator of the speech paths and the protocol converter for the PHS protocol and the Q.931 protocol. It has Dual Tone Multi Frequency (DTMF) senders for dialing to the Local Exchange (LE) through the Central Office Terminal (COT).
2-2 RPC Installation RPC/RP Manual Figure 2-1: RPC in the WLL System 2.1.1 Main RPC Features An RPC consists mainly of four types of function modules: • • • • One ECNT (Enhanced Control) module Up to four E1IF (E1 Interface) modules Up to eight RPIF (RP Interface) modules One APL (Application Software Loading) module - Optional Figure 2-2 displays the four types of the function modules in the RPC. WLL-RPC/RP-IN/UM-1.
RPC/RP Manual RPC Installation 2-3 Figure 2-2: Function Modules inside the RPC Each RPC can handle traffic loads of up to 120 simultaneous telephone calls. Four E1 trunks connect to the COT side and support 30 subscriber channels each. In normal traffic conditions, a single RPC can service approximately 1000 subscribers. The RPC is monitored and controlled from the network management system connected to the COT.
2-4 RPC Installation RPC/RP Manual 2.1.2.1 Enhanced Control Module The ECNT module provides the Operation, Administration and Maintenance (OA&M) support for the RPC. In addition, it provides the time slot cross connect switch for communications between the E1IFs and the RPIFs. Figure 2-3 represents the ECNT functions.

2-6 RPC Installation RPC/RP Manual Rec.726 compliant, from the RP. It supports 32 kbps channel signaling for encoded voice and voice band data calls. In addition, the E1IF communicates internally with the Radio Port Interface (RPIF) module for interfacing RPs through the backplane busses and the switch in the ECNT module. The E1IF module is an E1 module (E1M) that provides 4 E1 connections to the E1 network. The E1 module has the following functions: • • • • • • Originates/terminates 4 G.703/G.704 2.
