Parameter Reference
3.16.1 Serial Mode (Master/Slave)
Description: Specifies if the Media Gateway is using the Serial protocol and, if so, whether the
unit is the Serial Protocol Master or Slave. The Media Gateway must be configured as the Master if
it is physically connected to the Serial link of the PBX. In a system with multiple Media Gateways,
only one of the units can be connected to the Serial link of the PBX. This unit is the Serial Protocol
Master and all other Media Gateways are considered to be the slaves.
Note: The master and slaves use the IP network to communicate Serial protocol information to each
other.
Allowed Values:
• None = Serial link is not used.
• Master = This Media Gateway is connected to the PBX Serial link.
• Slave = This Media Gateway is part of a multiple configuration, but is not connected to the
PBX Serial link.
Default Value = None

Serial Mode parameter is set to Master.
Allowed Values:
• SMDI
• MCI
