3.14.5 Interface Cable

The RT-Router 4-Port E1 IMA MIM provides four E1 ports and adopts a 120-ohm or a 75-ohm Router 4-Port E1 IMA MIM conversion cable. The two types of cables have similar appearance. Both of them have a DB68 connector at one end used to connect a router. While at the other end, the 75-ohm Router 4-Port E1 IMA MIM conversion cable can be connected with eight coaxial cables; and the 120-ohm Router 4-Port E1 IMA MIM conversion cable can be connected with four twisted pairs.

3.14.6 Connection of the Interface Cable

Perform the following procedure to connect the RT-Router 4-Port E1 IMA MIM interface cable:

1)Choose an appropriate type of IMA-8E1/Router 4-Port E1 IMA MIM cable

depending on the interface type of the peer device.

zIf the interface impedance of the peer device is 75 ohm, use a 75-ohm  Router 4-Port E1 IMA MIM conversion cable.

zIf the interface impedance of the peer device is 120 ohm, use a 120-ohm  Router 4-Port E1 IMA MIM conversion cable.

2)Insert the Router 4-Port E1 IMA MIM conversion cable at the DB68 end to the DB68 port of the Router 4-Port E1 IMA MIM interface card, and fasten the fixed screws of the cable.

3)Check the serial number of the other end of the IMA-4E1 conversion cable and connect it with an E1 cable.

4)Connect the E1 cable with a peer device.

5)Check the slot-corresponding LED on the front panel of the router after power-on. If the LED lights, it indicates the interface card passed the self test and operates normally. If the LED is off, it indicates the interface card did not pass the self test, in this case, contact your agent.
