Digital Trunk Support: Units and Modules

The digital trunk modules and Network Service Unit provide connectivity to digital trunks for

public or private networks. The following table summarizes digital trunk support for the

controllers.

Dual Fiber Interface Module (FIM)

The Dual FIM module allows you to connect

• NSUs to the MXe III Controller and AX Controller

• Peripheral Cabinets and bays to the MXe III Controller

Each Dual FIM allows you to connect up to two NSUs or two Peripheral Cabinets to the controller.

The NSUs or Peripheral Cabinets connect to the controllers via fiber optic cabling. The fiber

optic cabling allows units or cabinets to be located up to 14 km from the controller.

R2 Network Services Unit

R2 is a protocol converter that allows the R2 NSU to access an R2 National Public Switched

Telephone Network (PSTN) using MF-R2 digital trunk signaling. The 3300 Controller also

receives and processes Calling Line Identification (CLI) and allows the information to be

displayed on the user's phone display screen.

Dual T1/E1 Module

The Dual T1/E1 module, supported in the MXe III and AX, is a digital trunk interface that supports

the direct connection of ISDN-PRI, T1/D4, QSIG, MSDN/DPNSS, and IDA-P trunks to the

controller. This module has two ports supporting two digital links. Each port can support a

different protocol.
