Version 7.2 1145 Mediant 500 MSBR
User's Manual 74. Configuration Parameters Reference
Table 74-60: ISDN Parameters
Parameter Description
ISDN Termination Side
configure voip > interface e1-
t1|bri > isdn-termination-side
[TerminationSide]
Determines the ISDN termination side.

[0] User side = (Default) ISDN User Termination Equipment
(TE) side.

[1] Network side = ISDN Network Termination (NT) side.
Note: Select 'User side' when the PSTN or PBX side is
configured as 'Network side' and vice versa. If you don't know the
device's ISDN termination side, choose 'User side'. If the D-
channel alarm is indicated, choose 'Network Side'.
The BRI module supports the ITU-T I.430 standard, which defines
the ISDN-BRI layer 1 specification. The BRI and PRI ports are
configured similarly, using the parameter. When an NT port is
active, it drives a 38-V line and sends an INFO1 signal (as
defined in ITU-T I.430 Table 4) on the data line to synchronize to
a TE port that might be connected to it. To stop the voltage and
the INFO1 signal on the line, stop the trunk using the Stop Trunk
button.
[TerminationSide_x] Same as the description for parameter TerminationSide, but for a
specific trunk ID (where
x denotes the Trunk ID and 0 is the first
Trunk).
Enable ignoring ISDN
Disconnect with PI
ign-isdn-disc-w-pi
[KeepISDNCallOnDisconnect
WithPI]
Enables the device to ignore ISDN Disconnect messages with PI
1 or 8.

[1] = The call (in connected state) is not released if a Q.931
Disconnect with PI (PI = 1 or 8) message is received during
the call.

[0] = (Default) The call is disconnected.
PI For Setup Message
pi-4-setup-msg
[PIForSetupMsg]
Determines whether and which Progress Indicator (PI) information
element (IE) is added to the sent ISDN Setup message. Some
ISDN protocols such as NI-2 or Euro ISDN can optionally contain
PI = 1 or PI = 3 in the Setup message.

[0] = PI is not added (default).

[1] = PI 1 is added to a sent ISDN Setup message - call is not
end-to-end ISDN.

[3] = PI 3 is added to a sent ISDN Setup message - calling
equipment is not ISDN.
B-channel Negotiation
configure voip > interface e1-
t1|bri > b-ch-negotiation
[BchannelNegotiation]
Defines the ISDN B-channel negotiation mode.

[0] Preferred

[1] Exclusive (default)

[2] Any
Note:

For some ISDN variants, when 'Any' (2) is selected, the Setup
message excludes the Channel Identification IE.

The Any' (2) option is applicable only if the following conditions
are met:

The parameter TerminationSide is set to 0 ('User side').

The PSTN protocol type (ProtocolType) is configured as
Euro ISDN.
ISDN Flexible Behavior Parameters
ISDN protocol is implemented in different switches/PBXs by different vendors. Several
