Mediant 3000
Parameter Description

[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.
Web: External Interface Type
EMS: External IF 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
Web: T1 External Reference
Transmit Line Build Out
EMS: T1 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: This parameter is applicable only when using BITS
Synchronization (i.e., the parameter TMMode is set to 1).
Web: E1 External Reference
Transmit Line Build Out
EMS: E1 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: This parameter is applicable only when using BITS
Synchronization (i.e., the parameter TMMode is set to 1).
Web: Reference Validation
Time
EMS: Validation Time
[TMReferenceValidationTime
]
Defines the Reference validation time.
The valid range is 0 to 15 minutes. The default is 1 minute. The
resolution is 1 minute.
Note: This parameter is applicable only for External timing (i.e.,
BITS) and Line timing references (refer to the parameter
TMMode).
