Overview

LNK-PH32-4E1-4ETH is a new generation highly-integrated single-board PCM base group multi-connection equipment based on independent software and thick & thin film technology. It can provide a 32-line voice interface directly upon the optical transmission channel with a 4-line E1 interface, a 4-line (100Mshared) Ethernet data interface. Voice Broadband Optical Multiplexer is mainly used in implementing connections between telephones and SPC exchanges through transmission network, as well as providing various kinds of data operation interfaces.

The device is widely used in: places such as telephone bars, middle and small scale companies, expressways and some temporary construction sites which demand quick solutions to the need of telephone and data operation, and the “Village-village Connection” telephone accessing project which is now in progress.

Features
High-density single-board design, improved system reliability, easy installing & commissioning, maintenance free and stable performance.
Fiber interface provides optical circuit E-3 and E-6 bit error warning detection, indicating circuit quality for builders and helping circuit maintenance.
4-line E1 interface, and E1 resistance can support 75 Ohm balanced or 120 Ohm (optional) unbalanced resistance.
32-line telephone interface, traditional PSTN voice, uncompressed, with high voice quality. Caller ID functions available.
4-line Ethernet interface with100Mbandwidth. Optional10M/half duplex,10M/full duplex,100M/half duplex,100M/full duplex and self adaptative.
Peer-to-peer networking mode, FXO/FXS mode supported. Fixed the telephone transmission problems of marginal customers.
The voice adopts PCM coding and a bandwidth of 64 kbps; it can support polarity reversal and caller ID display and support hotline;
The equipment supports double power versions of AC220V and DC48V.
