Port Configuration Jumpers
The T1/E1 CSU/DSU I/O Card has connectors to mount either a T1 or E1 Line
Interface Driver (LID). The I/O also has a number of 2-pin connectors that can be
modified with suitcase jumpers to select the port and match line impedance. For
T1, the I/O must be configured for connection through the RJ-48 connector. For
E1, the I/O can use either the RJ-48 or the two BNCs, depending on the network.
When the correct port has been selected the line impedance can be set.
Table 19-1 describes the jumper configurations required to select either the RJ-48
or the BNC connectors. Table 19-2 and Table 19-3 describe the jumper
configuration required to match the correct line impedance.
.
The following table describes the jumper settings for the correct line impedance
for T1 through the RJ-48 connector.
