Function
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.
