LINK/ACT
• On means carrier signal has been received.
• Flashing means data is being received or/and transmitted.
• Off means no carrier signal has been received.
LP/AL
• On means the interface is in a loopback.
• Flashing means an AIS, LFA, or RAI alarm signal is present.
• Off means no loopback or alarm is present.
Note:
AIS = Alarm indication signal; LFA = loss of frame alignment; RAI = Remote alarm indication

MIM-1CE3
Introduction
The 1-port channelized E3 interface module (MIM-1CE3) provides the following features:
• Transmits and receives and handles one channel of E3 fast traffic, and provides access to 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.
E3 represents the tertiary group rate of
E system in the TDM system:
34.368Mbps. An E3 channel
can be channelized into 16 E1 lines through the demultiplexing processes of E23 and E12
. E
s both E1 and CE1 modes. E23 is used to indicate either E2-to-E3 multiplex or E3-to-
tiplex, and E12 to indicate E1-to-E2 multiplex or E2-to-E1 demultiplex. "E23" and "E12"
discussed here represent the demultiplex process.
