Configuring the 56/64 Kbps CSU/DSU WAN Port (Model 45x and 55x)

This section describes how to set the baud rate for the 56/64 Kbps CSU/DSU port.

Before beginning this procedure, complete the following tasks:

■Cable the 56/64 Kbps CSU/DSU port and connect it to the telephone network.

■Log on to the system with Network Manager privilege.

The default baud rate is 64 Kbps. Change the baud rate if necessary using:

SETDefault !3 -PATH Baud = <kbps> (56 or 64)

Re-enable the path by entering:

SETDefault !3 -PATH CONTrol = Enabled

Configuring the T1/FT1 RJ-48 Telco Port (Model 46x and 56x)

This section describes how to configure the T1/FT1 RJ-48 Telco port.

Before beginning this procedure, complete the following tasks:

■Cable the T1/FT1 RJ-48 Telco port and connect it to the telephone network.

■Log on to the system with Network Manager privilege.

To configure the T1/FT1 RJ-48 Telco port, follow these steps:

1Select the channels that are mapped to the Fractional T1/T1 channel using:

ADD !<path> -PATH T1ChannelMap <path number> (1-24)

Where <path number> is the DS0 channel you are adding.

2Set the T1 line distance using:

SETDefault !<path> -PATH T1LineDistance = [LH1 LH2 LH3 LH4

SH1 SH2 SH3 SH4 SH5]

The following table lists the values associated with these options.

LH1 = 0 db	SH1 = 0 - 133 feet
LH3 = 15 db	SH3 = 266 - 399 feet
LH2 = 7.5 db	SH2 = 133 - 266 feet
