4 – Frame Relay Set-Up
The Frame Relay Set-up option takes you to the Frame Relay Set-up menu where autolearning may be disabled and LMI
parameters set.
Note: this option appears only if the router has a leased line module installed on this link and Logical Leased Type is set to
FrameRelay.
The following option appears if a G703 interface module is installed on this link:
4/5- Link mode
The Link mode option sets the clock mode for a G703 interface on the link.
Default: [master]
Choices: master, slave
4/5 – T1/E1 Set-Up
If this P1700 has a T1/E1 interface, this option takes you to the T1/E1 Set-up menu where T1/E1 parameters may be
configured.
4/5/6 - Link Speed
The Link Speed option allows you to define the clock speed generated internally by the bridge/router for the link.
The link will clock both transmit and receive data from the clock it receives from the DCE device.
This internally generated clock may be used to clock this bridge/router and a partner bridge/router by using a custom
back-to-back cable to connect the two bridge/routers together. This back-to-back connection is usually required only
for testing purposes.
Choices: 9.6, 14.4, 19.2, 48, 50, 56, 64, 72, 76, 100, 128, 256, 384, 512, 768, 1024, 1544 and 2048 Kbps.
Default: [64 kbps]
Considerations:
The speed option is not available when an LXT441-CSU module is installed for this link.
4/5/6/7 - Link CD Wait Time
The Link CD Wait Time option specifies the time the bridge/router will wait for Carrier Detect on the link. This is
used primarily when modems must cycle through various speeds to find the one used for the link.
Default: [60 sec]
Range: 0 to 255 seconds
Considerations:
The CD wait time option is not available when an LXT441-CSU or T1/E1 module is installed for this link.
