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
