10.6.1 Functions and appearance

Panel
The HT-8FE16E1 card supports reverse multiplexing on 8 Ethernet
interfaces. Up to 8 E1s can be used as reverse multiplexing channels for
each Ethernet interface. PCM31 mode transmission is fixed for multiple
ways of E1 reserve multiplexing. Each Ethernet interface can use a
single E1 for transmission in unframed or PCM31 mode.
The HT-8FE16E1 card provides the following functions:

Provide 8 independent Ethernet interfaces.

Support single E1 transmission in unframed or PCM31 mode.

Support reverse multiplexing. Up to 8 E1s can be used as reverse
multiplexing channels for each Ethernet interface in PCM31 fixedly,
 Ethernet interfaces 1–4 can use No. 1–8 ways of E1 services only in
reserve multiplexing.

Ethernet interfaces 5–8 can use No. 9–16 ways of E1 services only in
reserve multiplexing.
 Support E1 channel loopback, including local external loopback and
remote external loopback.
 Support querying LOS, AIS, CRC, and GID-ERR alarms.
 Support inhibiting or adaptively detecting CRC frames.
 Support statistics of error codes for E1 channels.
 Support cooperation between error code statistics and loopback.
Execute remote external loopback before enabling BERT. Disable
BERT before release loopback.
 Support automatic adjustment of bandwidth through LCAS-LINK
mechanism.
The 300-W power supply card is required.
