Description
Loop
<X01-X04>
Each BRI module supports four loops (eight lines for T-loop programming).
Type
T
S
This setting defines whether the loop supports trunks (T-loop) or device
connections (S-loop).
Note: This variable may be different for different market profiles.
Protocol
Euro
QSIG
NI-2
Select the appropriate ISDN protocol.
The values displayed depend on both the market profile and software
keycodes.
Euro - ETSI ISDN standard
QSIG - also an ETSI standard. Only appears if the ETSI QSIG keycode is
loaded.

Sampling
(S-loops
only)
Adaptive
Fixed
N/A
Select a sampling rate for the S-loop.
Fixed: two or more S-interface devices use the loop, and the length of the
loop is less than 200 m (650 ft.).
Adaptive: two or more S-interface devices use the loop, and the length of
the loop is greater than 200 m (650 ft.). If one device is using the loop, the
length of the loop can be a maximum of 1000 m (3230 ft)
