Interface cable

The MIM-8E1(75) or MIM-8E1(75)-F provides eight E1 ports and uses a 75-ohm splitter cable. At one

end of this 16-core coaxial cable is a DB-68 connector used to connect to the device, and at the other

end are 16 BNC connectors used to connect to the peer devices.

NOTE:

• The MIM-8E1(75)/MIM-8E1(75)-F does not support ISDN PRI.

• For the MIM-8E1(75), if you use the timeslot binding command on the controller E1 interface, the

system automatically creates a serial interface, on which the configuration takes effect. The

MIM-8E1(75)-F does not have any controller E1 interfaces, and a physical interface corresponds to one

and only one serial interface, which is automatically created without the need of additional

configuration.

• For the appearance and connection of a MIM-8E1(75)/MIM-8E1(75)-F interface cable, see

"Connecting an E1 interface cable."

MIM-8T1/MIM-8T1-F

The MIM-8T1 is an 8-port channelized T1 interface module, which transmits, receives, and processes

eight channels of T1 data, and supports CT1 access.

The MIM-8T1-F is an 8-port non-channelized T1 interface module. It differs from the MIM-8T1 in these

ways:

• The FT1 operating mode supported by the MIM-8T1-F allows only one n × 64 kbps OR 56 kbps

bundle to be formed on each interface, where n is in the range 1 to 24.

• The MIM-8T1 allows arbitrary grouping of 24 channels and thereby multiple bundles.
