9.4.5 Modem Global Configuration (MGC) Command and Query

The MGC command/query can be used to configure/report on the whole modem or parts of the modem. It contains
spare bytes for future development, but the length is fixed to 255 bytes. MGC can be used with modulator-only units,
demodulator-only units, and modem units.
9.4.5.1

MGC Format

The format for the MGC command/query is as follows:
MGC=TRUSI[Tx Block][Rx Block][Unit Block][Slot Identifier][Interface Block].
For a command, the first 5 bytes indicates whether the corresponding block should be configured:
T – 'T' means you should change the Transmit (Tx) configuration; '0' means you should skip the Tx configuration.
R – 'R' means you should change the Receive (Rx) configuration; '0' means you should skip the Rx configuration.
U – 'U' means you should change the Unit configuration; '0' means you should skip the Unit configuration.
S – Indicates which Interface Slot should be enabled: '1' indicates that you should enable Interface Slot 1; '2' indicates
that you should enable Interface Slot 2.
I – Indicates which interface type is active for the Interface block: '1' indicates CDI-40 ASI Interface; '2' indicates
CDI-70 Gigabit Ethernet Interface (GBEI); '3' indicates CDI-60 HSSI Interface.
For a query, the first 5 bytes indicates whether the corresponding block is present in the response:
T – 'T' if transmit block is present; '0' means the block is not present and 'x's are returned.
R – 'R' if receive block is present; '0' means the block is not present and 'x's are returned.
U – 'U' if unit block is present; '0' means the block is not present and 'x's are returned.
S – Indicates which interface slot is enabled: '1' indicates Interface Slot 1; '2' indicates Interface Slot 2.
