ARSE
The CM-1056E, Larse S5600, and Racal-Milgo 4556 are all nearly identical CSU/DSU's, and are used
exclusively for leased-line operation. Set the switch settings as follows (the numbers are not given,
because they vary from model to model):
Switch Function
CTS
DTE
Remote digital loopback
Stream
RTS
DSR loopback
Circuit assurance
Clocking
Before performing any back-to-back testing, obtain a 2-pair (4 wire) RJ-45 cross-over cable, with pin 1
connected to pin 8, and pin 2 connected to pin 7.
If these CSU/DSUs will be used on a public data network (instead of a leased line), set the clocking
function to OFF, because the CSU/DSUs will receive their timing from the DDS network.
D.6.4 M TA220/TA220
OTOROLA
The Motorola ® TA220s provide service over ISDN lines, but do not provide internal termination, and so
require a NT1 connection. The TA220/220k's can be used simultaneously with other ISDN equipment
over the same digital line.
Using the V.35 adapter provided with the TA220, connect the Router Sync+ to the RS-232 port #1 on
the TA220. Configure the TA220 for V.35 operation.
Using the TA220's front keypad, load the factory-default setting 0. Set the SWITCH CONFIG options,
according to the type of service available. Contact your service provider for more information about the
switch type.
After loading the factory default, change the PORT CONFIG OPTIONS as specified:
DTE options:
• port 1:
• speed:
• DTE CMD and MESSAGE OPTIONS:
• DTE PIN OPTIONS:
