Version 7.0 971 Mediant 3000
User's Manual 58. Configuration Parameters Reference
Parameter Description
The parameter is applicable to Mediant 3000 systems housing
TP-8410 blades. For Mediant 3000 systems housing TP-6310
blades, configure the parameter to [0] to use a 12 ppm
reference.
Timing Module Mode
[TMMode]
Determines the device's Timing Synchronization mode.
[0] StandAlone = (Default) Standalone Synchronization mode -
without using the SAT timing module.
[1] External = External, where each blade is synchronized from
one of the PSTN interfaces (without using the SAT timing
module). This must be selected for the BITS Synchronization
mode.
[2] LineSync = Line Synchronization mode - synchronizes the
device with one of the PSTN interfaces.
External Interface Type
[TMExternalIFType]
Defines the external BITS reference transmission type for both
primary and secondary interfaces.
[0] E1 CRC4 (default)
[1] E1 CAS
[2] E1 FAS
[3] T1 D4
[4] T1 ESF
[5] T12
T1 External Reference Transmit
Line Build Out
[TMT1LineBuildOut]
Defines the transmission power between the timing module on the
SAT blade
and the T1 external reference clock (External Reference
Transmit Line Build Out).
[0] = DSX 1.0 to 133 feet 0 dB CSU
[1] = (Default) DSX 1.133 to 266 feet
[2] = DSX 1.266 to 399_feet
[3] = DSX 1.399 to 533 feet
[4] = DSX 1.533 to 655 feet
[7] = DSX 1.0 to 133 feet 0 dB CSU pluse enable transmit and
receive gapped clock
Note: The parameter is applicable only when using BITS
Synchronization (i.e., the parameter TMMode is set to 1).
E1 External Reference Transmit
Line Build Out
[TME1LineBuildOut]
Defines the transmission power (in ohm) between the timing
module on the SAT blade and the E1 external reference clock.
[0] E 75 ohms normal
[1] E 120 ohms normal (default)
[4] E 75 ohms with high return loss
[5] E 120 ohms with high return loss
[6] E 75 ohms normal plus enable transmit and receive gapped
clock
[7] E 120 ohms normal plus enable transmit and receive
gapped clock
Note: The parameter is applicable only when using BITS
Synchronization (i.e., the parameter TMMode is set to 1).
Reference Validation Time Defines the Reference validation time.
The valid range is 0 to 15 minutes. The default is 1 minute. The
