MIM-1CE3(RT-MIM-1CE3-V2-H3)
The MIM-1CE3 is a 1-port channelized E3 interface module. It has the following features:
• In E3 mode, it transceives and processes high-speed data streams over the E3 channel, and
provides access to E3 data streams.
• In CE3 mode, it provides the low-speed access service at N × 64 kbps, where N is smaller than or
equal to 128.
NOTE:
•
E3 represents the tertiary group rate of the E series in the TDM system, which is 34.368 Mbps.
• An E3 channel can be channelized into 16 E1 channels through the demultiplex processes of E23 and
E12, with each E1 channel supporting both the E1 and CE1 operating modes. E23 indicates either
E2-to-E3 multiplex or E3-to-E2 demultiplex, and E12 indicates E1-to-E2 multiplex or E2-to-E1
demultiplex. E23 and E12 discussed here represent the demultiplex process.
