User's Manual 72. Configuration Parameters Reference
Parameter Description
Note:
 Instead of configuring the parameter, it is recommended to use
the parameter ISDNTimerT310.
 The 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 value other
than 0, it overrides the timer with this value.
Note:
 For the parameter to take effect, a device reset is required.
 The parameter is applicable only to the QSIG variant.
[ISDNJapanNTTTimerT3JA] Defines the T3_JA timer (in seconds). The 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 value is -1 to 300. The default is 0 (meaning 50 sec).
The value -1 means that no timer is activated.
Note:
 This timer is also affected by the parameter
PSTNAlertTimeout.
 The parameter is applicable only to the Japan NTT PRI variant
(ProtocolType = 16).
Trace Level
configure voip > interface e1-
t1|bri > 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
Framing Method
configure voip > interface e1-t1 >
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.
