Mediant 1000B Gateway & E-SBC
Parameter Description
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
[KeepISDNCallOnDisconnectWithPI]
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.
= (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
ISDN Flexible Behavior Parameters
ISDN protocol is implemented in different switches/PBXs by different vendors. Several
implementations may vary slightly from the specification. Therefore, to provide a flexible interface that
supports these ISDN variants, the ISDN behavior parameters can be used.
Incoming Calls Behavior
configure voip > interface e1-t1|bri >
isdn-bits-incoming-calls-behavior
[ISDNInCallsBehavior]
Determines the bit-field used to determine several behavior
options that influence how the ISDN Stack INCOMING calls
behave.
[32] DATA CONN RS = The device automatically sends a
Q.931 Connect (answer) message on incoming Tel calls
