System
Before configuring the Network T1/DSX-1 interface of the SLC ConnectReach
system, you must determine how the DS1 signal on the network carrier facility has
been configured by the carrier.
The key commands that must match the carrier's configuration are as follows:
Framing Format
Line Coding
The SLC ConnectReach systems equipped with
software earlier than R3.6.3 support the three most
common T1 framing formats: Extended Superframe
(ESF), Superframe (SF or D4), and the Bellcore
defacto standard frame adapted to a single T1 link
(TR-TSY-000008 or TR08). However, the ESF framing
format should always be selected to assure
compatibility with the SLC-2000 Access System
remote terminal/host digital terminal (RT/HDT).
This command is not available in SLC ConnectReach
systems equipped with software R3.63 and later. The
framing format defaults to ESF.
The T1 line coding formats offered by the SLC
ConnectReach system are bipolar 8 zero substitution
(B8ZS) and alternate mark inversion (AMI). However,
the B8ZS line coding format should always be
selected to assure compatibility with the SLC-2000
Access System RT/HDT.
