Command or
Response to
Query
Command or Query.
This command is only valid for an EDMAC master.
When used as a Query, it may be sent to an EDMAC slave, which will respond with
the appropriate address.
EDMAC Slave Address Range - sets the range of addresses of distant-end units
(modems or transceivers) for which this unit, as the Master, will forward messages.
Only values which are integer multiples of ten are permitted. (0010, 0020, 0030,
0040, etc.).
Example: ESA=0090
Query only.
Unit returns the current highest-priority fault and status codes for the Unit
(hardware), Tx Traffic, Rx Traffic and ODU in the form abcdef, where:
a = Unit faults:
0 = No faults
1 = Power supply fault, +5 volts
2 = Power supply fault , +12 volts
3 = Power supply fault, –5 volts
4 = Power supply fault, +23 volts
5 = Power supply fault, –12 volts
6 = Tx synthesizer lock
7 = Rx 1st LO synthesizer lock
8 = Rx 2 nd LO synthesizer Lock
9 = Ref PLL lock
A, B, and C are TBD (for future expansion)
D = Reserved
E = IP Module
F = EEPROM checksum error
b = Tx Traffic status:
0 = Tx traffic OK
1 = No clock from terrestrial interface
3 = Tx FIFO slip
4 = G.703 Loss of Signal (only valid in Clock Extend Mode)
5 = Loss of External Reference
7 = AUPC upper limit reached
9 = AIS detected on incoming data
A = WAd E1 sync loss
B = Bipolar violation on G.703 interface
C = BUC Alarm (if attached)
