Introduction
The 1-port channelized E3 interface module (HMIM-1CE3) provides the following features:
•
Transmits, receives and handles one channel of E3 fast traffic, and provides access for E3
traffic when operating in E3 mode.
Provides low-speed accessing service at n × 64 kbps when operating in CE3 mode. n is smaller
•
than or equal to 128.
NOTE:
E3 represents the tertiary group rate (34.368 Mbps) of E system in the TDM system. An E3 channel
can be channelized into 16 E1 lines through the demultiplexing processes of E23 and E12. Each E1
line supports both the E1 and CE1 modes. E23 is used to indicate either E2-to-E3 multiplex or
E3-to-E2 demultiplex, and E12 to indicate E1-to-E2 multiplex or E2-to-E1 demultiplex. "E23" and
"E12" discussed here represent the demultiplex process.
