Controller Module Installation Notes

DSP Module

• Refer to "Increasing DSP Resources" on page 287.
• Make sure that you have sufficient compression licenses before
installing DSP modules for compression.
Dual Fiber Interface Module (FIM)
• Ensure that the type of the optical interface matches that of the mating
unit (820 nm multi-mode, 1300 nm multi-mode, or 1300 mn
single-mode).

Echo Canceller

• The CX, CXi, CX II, CXi II, MXe, MXe Server, and AX contain echo
cancellers on the main board that are sufficient to handle normal traffic
conditions.

Framers

Embedded T1/E1 (for PRI, T1/D4, or BRI)
• You can add embedded T1/E1 (for PRI, T1/D4, or MSDN/DPNSS) or
embedded BRI to a controller by adding one to three framer modules
(Dual T1/E1, T1/E1 Combo, or Quad BRI). (See "Hardware Part
Numbers" on page 371 for the part number of the Framer Modules.)
