Smart SS-PMS-02 Portable Multi-service Access Device

  General Introduction

Smart SS-PMS-02 is particularly designed and manufactured for special networks and access networks requiring multi-service access. Integrated with digital/analogue access and multiplexing function, it is applicable for special network construction for bank, electric power industry, public security and transportation etc, and as well as DDN network extension. Besides, the Ethernet interface of Smart Bx06 can realize connecting with LAN and WAN, and interlinking with remote LAN.

Product Feature

  •  Plenty selection of data interfaces: 64K (same direction), RS232, RS485, V.35 (N×64K), 10BaseT and Morse code;

  •   Complete audio interfaces: POTS, billing telephone, magnet, common battery, hot line, carrier wave, E/M and 2/4 line audio;

  •   Local/remote compatible: either line of the same interface card can be set as switcher interface or user interface;

  •   Able to intercommunicate with PCM rack supplied by any manufacturer;

  •  Caller ID display；

  •   Hot swap；

  •  Comprehensive and block-free cross-connect capacity;

  •  Powerful ADM function, able to distribute time slots in 2M bandwidth at discretion so as to sufficiently employ 2M resource;

  •   Access to the switcher (MD110, MD150, HARRIS20-20) emulation PCM (2M) port in a peculiar single-sided suspension mode; 

  •   ADM mode shoot through on power down；

  •   Perfect test and alarm function, to implement real-time monitoring on the overall network via PC monitoring platform.

 

 Typical Application

  •  DDN network extension

  •  Narrow/broad band comprehensive access for residence community / intelligent mansion

  •  Multi-service access network construction for bank, electric power industry, public security and transportation etc

  •  Connecting with LAN and WAN, and interlinking with remote LAN
