The connecting picture of Single E1 card&external equipment
The single E1 card(type:1 port of Channelized mode and Unchannelized mode, Balanced and Unbalanced)supplies 1 DB15 interface .The interface card supports Unbalance(75-ohm)and Balance(120-ohm)terminal impedances, and relevant 75M with BNC connector cable and 120M with BNC connector cable .There are Channelized(rate:n×64Kbps,n=1~31)and Unchannelized(rate:2Mbps)communication mode.DB15 interface has the feature of inserting with the power ON,avoiding body static electricity and the thunder.
Note: The single E1 card can installed on the slot2 of 1750/2620 routers and
slot1 of 2621/2630/2650 router.The more information refers to the "Guides
