If you are unsure of your line's characteristics, try the following defaults:
4.
Select the correct T1 line build out value (US only). If you are using an external CSU, specify a
short haul build out (line length in meters). If you do not have an external CSU, specify a long
haul build out (decibel attenuation value from Telco).
5.
A data link is assigned to the line upon completion of the line configuration. Add more data
links or modify the existing data link.

Only if you plan on using X.25 over the D-Channel on this line, answer yes to the following
prompt:
b.
Assign a TEI Negotiation value of 0.
Note:
If you select E1/R2 signaling for your framing type, you will not be asked to configure
datalinks (items 4 and 5). R2 signaling does not make use of a datalink; all datalinks
associated with the line are automatically deleted.
If you select a Robbed Bit line, CFGEDIT will inform you that RBS will delete any datalinks
on the line. The system will prompt you to confirm this deletion, and then automatically
delete the datalinks.
