Interface cables
The MIM-1CE3 provides two SMB interfaces, with one interface acting as the transmission end (Tx) and
the other as the receiving end (Rx). The Tx and Rx interfaces operate in the 75-ohm unbalanced
transmission mode and thereby need a pair of 75-ohm unbalanced coaxial cables in use for connection
with the peer device.
NOTE:
•
The MIM-1CE3 and MIM-1CT3 use the same type of E3/T3 cable.
• The E3/T3 cable is an optional accessory for the MIM-1CE3 to be separately ordered if needed.
• For the appearance and connection of an E3/T3 cable, see " Connecting a CE3/CT3 interface cable .

MIM-1CT3 (RT-MIM-1CT3-V2-H3)
The MIM-1CT3 is a 1-port channelized T3 interface module. It has the following features:
• In T3 mode, it transceives and processes high-speed data streams over the T3 channel, and
provides access to T3 data streams.
• In CT3 mode, it provides the low-speed accessing service at N × 64 or N × 56 kbps, where N is
smaller than or equal to 128.
NOTE:
•
T3 represents the tertiary group rate of the T series in the TDM system, which is 44.736 Mbps.
• A T3 channel can be channelized into 28 T1 channels through the demultiplex processes of T23 and
T12, with each T1 channel supporting both the T1 and CT1 operating modes. T23 indicates either
T2-to-T3 multiplex or T3-to-T2 demultiplex, and T12 indicates T1-to-T2 multiplex or T2-to-T1 demultiplex.
T23 and T12 discussed here represent the demultiplex process.
