5.1.8 T1/E1 Multiplexer
The Canopy T1/E1 Multiplexer
converts the data stream from T1/E1
ports into Ethernet packets that are
then transported over the Canopy BH
link. This enables up to four T1 (or up
to three E1) circuits to be extended
over Ethernet networks. The T1/E1
Multiplexer is available in two power
configurations:
◦ an external 3.3-v DC power
source from a 120/240-v AC
adapter (supplied
by Canopy)
◦ an optional connection to an
external −48 v DC supply for
battery backup.
The T1/E1 Multiplexer supports
◦ synchronous TDM-based
services over wireless
Ethernet networks.
◦ CAS signaling transparent to
all other signaling protocols
on T1/E1.
◦ 10Base-T/100Base-TX uplink
to the network.
◦ management interfaces.
◦ simplified troubleshooting
through T1/E1 line loopback
test.
