TDM-based system for voice and data multiplexing

FlexGain 4XE Compact Cross-connect

FlexGain 4XE

The FlexGain 4XE cross connector designed for switching 64 Kbit/s time slots of four E1 G.703 streams (2048 kbit/s) in telecommunication networks. FlexGain 4XE works either in PCM30 mode with the processing of TS No 16 or in the PCM31 mode with the normal switching of this time-slot. This allows device usage both in networks with channel associated signaling (CAS) and in-slot signaling systems.

FlexGain 4XE is interoperable with Multiplexer FlexGain Plex and with Orion modems. It uses similar mechanics and management.

FlexGain Plex Compact Multiplexer

FlexGain Plex

The FlexGain Plex compact multiplexer designed for transmission of voice channels over E1 stream. It supports FXO or FXS lines as well as voice-band leased lines with E&M signaling. FXO and FXS interfaces exchange their statuses such as On/Off-hook, Ring, Busy, etc. through sugnalling time-slot 16. CAS signaling bits are used for it.

FlexGain Plex supports 4 or 8 voice channels. Leased-line voice channels can be used for interconnection of voice band analogue modems.
