User's Manual 54. Configuration Parameters Reference
Version 6.8 821 Mediant 500 E-SBC
Parameter Description

Instead of configuring this parameter, it is recommended to use
the parameter ISDNTimerT310.

This parameter is applicable only to Nortel DMS and Nortel
MERIDIAN PRI variants (ProtocolType = 14 and 35).
[ISDNTimerT301]
Defines the override T301 timer (in seconds). The T301 timer is
started when a Q.931 Alert message is received. The timer is
stopped when a Q.931 Connect/Disconnect message is received
from the other side. If no Connect or Disconnect message is
received within the duration of T301, the call is cleared.
The valid range is 0 to 2400. The default is 0 (i.e., the default T301
timer value - 180 seconds - is used). If set to any other value than
0, it overrides the timer with this value.
Notes:

For this parameter to take effect, a device reset is required.

This parameter is applicable only to the QSIG variant.
[ISDNJapanNTTTimerT3JA]
Defines the T3_JA timer (in seconds). This parameter overrides the
internal PSTN T301 timeout on the Users Side (TE side).
If an outgoing call from the device to ISDN is not answered during
this timeout, the call is released.
The valid range is 10 to 240. The default is 50.
Notes:

This timer is also affected by the parameter PSTNAlertTimeout.

This parameter is applicable only to the Japan NTT PRI variant
(ProtocolType = 16).
Web/EMS: Trace Level
[TraceLevel]
Defines the trace level:

[0] No Trace (default)

[1] Full ISDN Trace

[2] Layer 3 ISDN Trace

[3] Only ISDN Q.931 Messages Trace

[4] Layer 3 ISDN No Duplication Trace
Web/EMS: Framing Method
CLI: framing
[FramingMethod]
Determines the physical framing method for the trunk.

[0] Extended Super Frame = (Default) Depends on protocol
type:

E1: E1 CRC4 MultiFrame Format extended G.706B (same
as c)

T1: T1 Extended Super Frame with CRC6 (same as D)

[1] Super Frame = T1 SuperFrame Format (as B).

[a] E1 FRAMING DDF = E1 DoubleFrame Format - CRC4 is
forced to off

[b] E1 FRAMING MFF CRC4 = E1 CRC4 MultiFrame Format -
CRC4 is always on

[c] E1 FRAMING MFF CRC4 EXT = E1 CRC4 MultiFrame
Format extended G.706B - auto negotiation is on. If the
negotiation fails, it changes automatically to CRC4 off (ddf)

[A] T1 FRAMING F4 = T1 4-Frame multiframe.

[B] T1 FRAMING F12 = T1 12-Frame multiframe (D4).

[C] T1 FRAMING ESF = T1 Extended SuperFrame without
CRC6

[D] T1 FRAMING ESF CRC6 = T1 Extended SuperFrame with
CRC6
