RC3000-15 (P100R001) Hardware Description
7.3 P240×2L
7.3.1 Functions and appearance
Panel
The P240× 2L is an Ethernet service multiplexing card. It provides the
following functions:
 Provide 2 groups of PDH optical interfaces which are enabled with
APS. Each group of PDH optical interface multiplexes 8 ways of E1
services and 100Base-TX Ethernet service; wherein, 8 ways of E1
services are allocated to the 2 groups.
 Provide 8 ways of E1 services. The number of E1 services for each
group of optical interface is configurable and is 4 by default. The first
4 ways of E1 services of two groups correspond to 8 E1 interfaces on
the backplane.
 Support ALS on optical interface. By default, ALS is disabled.
 Support failover from the optical interface to the Ethernet interface. By
default, fault pass is disabled.
–
The triggers of failover include local LOS, local LOF, remote LOF,
and remote LOF. The triggers cannot be configurable.
–
When alarms are generated on the working optical interface, disable
4 FE electrical interfaces on the front panel.
–
When alarms are generated on all 4 optical interfaces in all
switching working mode, disable the working FE interface.
–
In Access VLAN or Tunnel VLAN working mode, you can disable
the corresponding working FE interface according to VLAN
configurations.

Support framed and unframed E1 mode. By default, framed E1 mode
is used.
 Support PCM30 and PCM31 modes. By default, PCM30 mode is used.
 Support signaling cross connection in framed E1 mode.
 Support E1 BERT. Only one of 8 BERTs can be enabled at a time.
 Support external loopback on optical interfaces.
 Support E1 local bidirectional loopback.
 Support network management of remote E1 module devices. E1
network management channel can be configured to SA4, SA5, or
independent timeslot; by default, it is SA5. Baud rate is configurable
and is 2400 by default.
 Provide 7 Ethernet interfaces naming FE1 to FE7. Wherein,
– FE1 to FE4 are the 4 FE interfaces on the front panel. They support
automatic negotiation of duplex mode and interface rate. They also
support flow control and rate limiting.
–
FE5 is the FX interface connected to the backplane. It is fixed to 100
Mbit/s in duplex mode. It does not support rate limiting.
–
FE6 and FE7 are for transmission.

Support managing remote devices, such as the RC3000 (versions B
and C), RC3000E, RCMS29 series, and RC86 series.
