22222222222222222222=PIIC Card 2 Configuration
Note 1: There are several possible types of PIIC interfaces
available. The first bit of each 20 bit field determines the PIIC
interface type. 0 means no interface detected, non zero means
an interface type was detected.
Note 2: If no interface is present, then the following bits will be
returned: 0UUUUUUUUUUUUUUUUUUU
Note 3: If an interface is detected but the interface type is set to
NONE, then the following bits will be returned:
20xxxxxxxxxxxxxxxxxx, where:
2 means G.703 interface detected
0 means NONE selected so its disabled.
Description Of PIIC Interface Types:
G.703 Interface Type Description in the form ABCDEFGHIJ
ssssssssss, where:
A=2 – G.703 Intfc detected
0 – no Intfc detected
B=G.703 Mode (E3 T3 STS1)
C=Tx Intf Clock Source
D=Rx Intf Clock Source
E=Intf Reference Clock
FGHIJ=Rx Buffer Size

Note: A=1,3-9,A-F reserved
Command only.
Causes the modem to retrieve a previously stored modem configuration from
Configuration Memory location defined by the one-byte argument (0 to 9).
Example: CLD=4 (load modem configuration from location 4 to be the active
configuration)
Command only.
Command causes the modem to store the current modem configuration in
Configuration Memory location defined by the one-byte argument (0 to 9).
Example: CST=4 (store the current configuration in location 4)
