Configuring the E1 Interface
When ASMi-52 includes a G.704 E1 port, you can configure the following
parameters:
• Selecting framing mode
 Unframed – Stream of bits at 2.048 Mbps
 G732N – Timeslot 0 contains sync word
 G732S transparent – 16 frames per multiframe, timeslot 16 is passed
transparently.
• Selecting time required for the E1port to return to normal operation after sync
loss:
 CCITT – As per requirements of ITU-T Rec.G.732
 Fast – After 1 sec
 62411 – As per requirements of AT&T TR-62411 (after 10 sec).
• Enabling generation and checking of check bits for the frames transmitted on
the E1 port (as per CRC-4 polynomial specified by ITU G.704). Check bits
generation is available only for the G732N framing mode.
• Mapping E1 timeslots – Assigning each timeslot to carry user’s data.
• Selecting a code transmitted to fill unused timeslots in the E1 frames.
The E1 port configuration is performed via the E1 Port Configuration menu.
