Our modular design enables plug-and-play services. You don't pay additional outlays until your customer base grows up.


• Power Supply Module
This module provides shelf and ring power, with functions of over current protection and DC input/output isolation. 1+1 power redundancy is operated when adding two power supply cards to the shelf (COT/RT).


• Main Processing Module (MPM)
MPM controls the synchronization clock, module communication, time slot assignment, performance monitor, alarm and alarm report, system self auto detection, system database and user interface.


• Expansion Link Module (ELM)
ELM helps service providers scale their networks. Installing the module at COT to connect to extension shelves, the system capacity can be expanded.


• Expansion Processing Module (EPM)
At the RT or extension shelves, EPM is needed for shelf connection, timing provision, and receiving commands from the main shelf.


• V5 Processing Module (V5P)
Provides a standard interface to the local switch in providing narrowband services in a efficient and cost effective way to end-users. Our V5P module supports V5.2 protocol and can provide up to four individual V5.2 (4xV5.2). Each V5.2 is capable of the maximum support to 16 E1 interfaces which provide up to 480 voice channels with non-concentration. This allows the service providers to provide both on-demand and leased line services, including PSTN Access, ISDN BRI/PRA, Analogue and Digital Leased Line.


• Packet Voice Module (PVM)
PVM provides trunk network interface supporting packet voice services. It uses a real-time cpu and powerful digital signal processors (DSPs) that support all functions needed to provide the highest levels of voice fidelity and quality.
