E1-4*POTS + 1FE + 2RS232 FiberMux(Desktop Tpye)

Type:FCC-E1O4F1R2/FCC-E1F1S4R2 Message

Description:E1-4 * telephone+FE+2RS-232/422/485/dry connect Support 4U rackmount

Product Description
              This device is a desktop there 4U rack card type which provides telephone outputs 1-4 1 Ethernet (bandwidth 2M) +2 way RS232 / 422/485 (or 4-way RS232 / 422/485). Equipment electrical part for the whole digital circuits machine reliability stability low power consumption high integration small size easy installation and maintenance. Many customers are telecommunications operators E1 leased lines used in computer networking this equipment can be rented at the E1 line opened a few road phone you can make free calls between headquarters and branch offices of this.
Functional Properties

◆   based on proprietary integrated circuits;

◆   alarm status can be monitored on the end;

◆   E1 interface complies with G.703 all-digital clock recovery and smooth phase-locked technology;

◆   support FXO voice port FXS ports and ports EM2 / 4 audio interface FXO port and PBX docking port and

      the user is connected to FXS telephone;

◆   providing four expansion interface can be extended from 1 to 4 asynchronous data such as RS232 / RS485 / RS422 / Manchester codes;

     or 1 to 8-way switch 1 to 4-way voice or two / four-wire audio etc.;

◆   Ethernet interface 10M / 100M full / half duplex fully adaptive support VLAN division;

◆   Each Ethernet ports support Auto-MDIX (cross / straight cable adaptation);

◆   1-4 road voice access support caller ID function and reverse polarity billing functions;

◆   Support Telephone Number mutual function of each site;

◆   E1 signal can be detected as a barrier to the end device is lost or shut E1;

◆   provide two kinds of clock ways: E1 master clock E1 line clock;

◆   provides three kinds of loopback: E1 local loopback (ANA) the Ethernet interface to the remote loopback (DIG)

      command peer Ethernet interface to the local loop (REM);

◆   There are pseudo-random code test function (PATT) to facilitate the opening line which can be when one of E1 BERT to use;

◆   E1 can support N * 64k (N = 1-32) rate that rate is adjustable from 64K-2048K;

◆   multiple power mode options: AC220V DC-48V / DC24V etc;
