Description of Arguments
Command or Query.
Set or return the PIIC interface card mode in the form sm, where:
s = Interface Slot, where:
1 = Slot 1
2 = Slot 2
m = Mode, where:
For G.703 PIIC module:
0 = NONE
1 = E3
2 = T3
3 = STS1
G703 PIIC settings other than none will also set the selected G.703 data rate. The unit will adjust the symbol
rate based on the modulation type, code rate, framing, and pilots to keep the selected data rate
For OC3 PIIC module:
0 = NONE
1 = OC3/STM-1
OC3 PIIC settings other than none will also set the modem data rate to 155.52 Mbps. The unit will adjust the
symbol rate based on the modulation type, code rate, framing, and pilots to keep the selected data rate.
NOTE: Commands are valid only with the appropriate PIIC interface as indicated above. In addition, the following
is true for various cards.
Example: ETS=11
sets G.703 PIIC module in Slot 1 to E3 mode
sets OC3 PIIC module in Slot 1 to OC3/STM-1 mode
MultiStream and Single Stream Modes:
To enable MultiStream Mode:
1. Disable all PIIC Interfaces.
2. Enable one or more Gigabit Ethernet Interfaces.
3. Set the SR, ModCod, etc. to meet your requirements.
4. Enable PIIC 1 or PIIC 2 or both interfaces.
To enable PIIC1 or PIIC2 in synchronous interface mode:
1. Disable all PIIC Interfaces.
2. Disable all Gigabit Ethernet Interfaces.
3. Enable PIIC1 or PIIC2.
GBEI 1, GBEI 2 and Optical Ethernet must all be disabled before a PIIC can operate in a synchronous
mode.
