E1 module Installation
This
section introduces E1
module.
Connecting picture of E1 module &outside equipment
1-port
E1 module(type:1
port of Channelized mode and Unchannelized mode E1/ISDN PRI Balanced and
Unbalanced) supplies one DB15 interface to the outside.2-port E1 module (type:1
port of Channelized mode and Unchannelized mode E1/ISDN PRI Balanced and
Unbalanced)supplies two DB15
interface to the outside.4-port E1 module(type:4
ports of Channelized mode and Unchannelized mode E1/PRI-Balanced and
Unbalanced)supplies four DB15 interface to the outside.The
module supports Unbalance(75ohm)&Balance(120ohm)tterminal
impedances and supplies 75ohm cable with BNC connector and 120ohm cable with RJ45 connector.There are
Channelized(rate:n×64Kbps,n=1~31)and Unchannelized(rate:2048Kbps) two kinds communication mode.DB15 interface has the feature of hot swap
and avoiding body static electricity and thunder.
