Media Module Administration and Options

The DS1 configuration for each Media Module is administered on the DS1 Media Module form. Bit Rate is set to 1.544 Mbps for 24-channel systems, and 2.048 Mbps for 32-channel systems. Country Protocol is used to drive layer 3 protocol decisions based on PRI specifications specific to a given country (not those related to specific features). This Country Protocol is independent of the Country parameter administered on the country-options system-parameters form. Different DS1-MM Media Modules may be administered with different Country Protocols, allowing the switch to act as a gateway between two incompatible ISDN-PRI implementations (for example, between two different countries). US systems use country protocol 1.
