Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
configure voip >
interface e1-t1|bri >
isdn-termination-side
[TerminationSide]
■ [0] User side = (Default) ISDN User Termination
Equipment (TE) side.
■ [1] Network side = ISDN Network Termination (NT) side.
Note:
■ If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
■ 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, select 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 by clicking Stop
Trunk.
'BRI Layer2 Mode'
configure voip >
interface bri > isdn-
layer2-mode
[BriLayer2Mode]
Defines Point-to-Point (P2P) or Point-to-Multipoint (P2MP)
mode for BRI ports.
■ [0] Point to Point (default)
■ [1] Point to Multipoint
Note: The parameter is applicable only to BRI interfaces.
'Q.931 Layer Response
Behavior'
configure voip >
interface e1-t1|bri >
isdn-bits-ns-behavior
[ISDNIBehavior]
Defines (by bit-field) several behavior options that influence the
behavior of the Q.931 protocol.
■ [0] = Disable (default).
■ [1] NO STATUS ON UNKNOWN IE = Q.931 Status
message isn't sent if Q.931 received message contains an
unknown/unrecognized IE. By default, the Status
message is sent.
Note: This value is applicable only to ISDN variants in
which sending of Status message is optional.
■ [2] NO STATUS ON INV OP IE = Q.931 Status message
isn't sent if an optional IE with invalid content is received.
By default, the Status message is sent.
Note: This option is applicable only to ISDN variants in
which sending of Status message is optional.
■ [4] ACCEPT UNKNOWN FAC IE = Accepts
unknown/unrecognized Facility IE. Otherwise, the Q.931
message that contains the unknown Facility IE is rejected
(default).
Note: This option is applicable only to ISDN variants
where a complete ASN1 decoding is performed on Facility
IE.
