Version 7.2 1233 Mediant 800B Gateway & E-SBC
User's Manual 72. Configuration Parameters Reference
Parameter Description
[PSTNExtendedParams] Determines the bit map for special PSTN behavior parameters:
 [0] = (Default) Applicable for NI-2 ISDN and QSIG
"Networking Extensions". This bit (i.e., bit #0) is responsible
for the Invoke ID size:

If this bit is not set (default), then the Invoke ID size is
always one byte, with a value of 01 to 7f.

If this bit is set, then the Invoke ID size is one or two
bytes according to the Invoke ID value.
 [2] = Applicable to the ROSE format (according to the old
QSIG specifications). This bit (i.e., bit #1) is responsible for
the QSIG octet 3. According to the ECMA-165 new version,
octet 3 in all QSIG supplementary services Facility
messages should be 0x9F = Networking Extensions.
However, according to the old version, the value should be
0x91 = ROSE:

If this bit is not set (default): 0x9F = Networking
Extensions.

If this bit is set: 0x91 = ROSE.
 [3] = Use options [0] and [2] above.
Note: For the parameter to take effect, a device reset is
required.
BRI Parameters
BRI Layer 2 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 = Must be configured for Network
side.
configure voip > interface
bri > tei-config-p2p
[BriTEIConfigP2P_x]
Defines the BRI terminal endpoint identifier (TEI) when in
point-to-point (P2P) mode.
The valid value is 0 to 63, 127. The default is 0.
 Network Side:

0-63: Static TEI is accepted.

127: Any possible TEI is accepted. Dynamic TEI
allocation is supported.
 User Side:

0-63: Static TEI is used.

127: Dynamic TEI allocation is supported (TEI request
procedure initiated).
Note: The value 127 replaces the previous configuration
requirement to set the ISDNIBehavior parameter to NS
EXPLICIT INTERFACE ID (1).
configure voip > interface bri > tei-
config-p2mp
[BriTEIConfigP2MP_x]
Defines the BRI TEI when in point-to-multipoint (P2MP) mode.
The valid value is 0 to 63, 127. The default is 127.
 Network Side: Not applicable - In network side in P2MP
configuration, any TEI must be accepted.
 User Side:

0-63: Static TEI is used.

127: Dynamic TEI allocation is supported (TEI request
procedure initiated).
