Using ISDN signaling
To configure an E1/PRI line for ISDN signaling in Belgium, the Netherlands, Switzerland,
Sweden, Denmark, or Singapore:
1 Open the Net/E1 > Line Config > Line Config profile > Line N subprofile for the line you
are configuring, and set the Sig Mode parameter to ISDN. For example:
Net/E1
Line Config
Line Config profile
Line 1...
Sig Mode=ISDN
2 Set the Switch Type parameter to Net 5 (the standard used in these countries):
Switch Type=Net 5
3 Specify G.703 framing (the standard used by most E1 ISDN providers):
Framing Mode=G.703
Note: If you select G.703, the MAX unit provides CRC-4 checking. If you select 2 DS, it
does not.
4 Exit the profile and, at the exit prompt, select the exit and accept option.
If the profile you have configured is not the active profile, activate it as described in
“Activating a profile” on page 2-7.
Using DPNSS signaling
To configure an E1 line for DPNSS signaling:
1 Open the Net/E1 > Line Config > Line Config profile > Line N subprofile for the line you
are configuring.
2 Set the DPNSS signaling mode and a compatible switch type. For example:
Net/E1
Line Config
Line Config profile
Line 1...
Sig Mode=DPNSS
Switch Type=Mercury
Mercury is a variant of DPNSS.
3 Set the framing mode. For example:
Framing Mode=2DS
Most E1 DPNSS providers in the U.K. require 2DS, which is a variant of G.703. If you
select G.703, the unit provides CRC-4 checking. If you select 2DS, it does not.
4 Make sure that the following parameters are set to their default values, as shown:
L3 End=x-side
L2 End=b-side
NL Value=64
LoopAvoidance=7
5 Exit the profile and, at the exit prompt, select the exit and accept option.
