Port Interface Modules 4-5

PIMs and BRIMs

APIMs

The Asynchronous Transfer Mode (ATM) Port Interface Modules, or APIMs, are

designed to allow connection to differing ATM networks, supporting not only

different media, but different speeds of ATM transmission. When selecting an

APIM, the Network Designer must ensure that the APIM supports both the

required media and the technology to be used. The media and technologies

supported by the available APIMs are listed below:

APIM-11: Multimode Fiber Optic TAXI connection

APIM-21: Multimode Fiber Optic OC3c connection

APIM-22: Single Mode Fiber Optic OC3c connection

APIM-29: Unshielded Twisted Pair STS3c connection

APIM-67: Thin Coaxial Cable DS3 connection

WPIMs

Wide Area Network Port Interface Modules, or WPIMs, act in much the same

manner as APIMs. Each WPIM is designed to provide connections to a particular

type of Wide Area Networking technology.

WPIM-SY: Synchronous link

WPIM-T1: T1 or Fractional T1 link

WPIM-E1: E1 or Fractional E1 link

WPIM-DDS: 56K link

WPIM-DI: Drop-and-Insert WAN link
