MCC1 Media Gateway
Note:
Note: The MCC1 is no longer sold, but is still supported.
An MCC1 Media Gateway can be used as a port network (PN) cabinet. Doors in front of and
behind the MCC1 Media Gateway protect the internal equipment and allow easy access to the
circuit packs. Each MCC1 Media Gateway rolls on casters. Leveling feet keep the cabinet from
rolling. Each lower corner of an MCC1 Media Gateway can be bolted to the floor, if required.
Detailed description
An MCC1 Media Gateway is a 70-inch (178-centimeter) cabinet that has up to five carriers.
MCC1 Media Gateways are one of four types:
● A DEFINITY Server SI PPN that contains the ports, SPE, an interface to an EPN, and
possibly a CSS.
● A PN or multiple PN configuration in an S8500 or S8700-series Media Server configuration
● A DEFINITY Server SI Expansion Port Network (EPN) that contains additional ports,
interfaces to the PPN cabinet and other EPNs, and the maintenance interface.
● A PN that contains a switch node, which is an SN in a system that has a CSS.
Carriers hold circuit packs and connect the circuit packs to power, the TDM bus, and the packet
bus. Carriers are one of five types:
● Control carrier (DEFINITY Server SI PPN only)
● Optional duplicated control carrier (DEFINITY Server SI PPN only)
● Optional port carrier (PPN, EPN, and PN)
● Expansion control carrier (EPN and PN)
● Optional switch node carrier (PPN, EPN, and PN)
