SX-200 ICP MX Technician’s Handbook

Cabinet Configuration Rules

The MX controller can be expanded to include:

• up to seven SX-200 Peripheral cabinets which provide 672 TDM ports

for ONS, OPS, DID, T1, PRI/T1

• up to four Universal NSUs which provide eight PRI Links (192 PRI/T1

trunks)

• up to two offboard ASUs which provide 48 ONS/CLASS circuits

3. Installation of a hard drive is strongly advised for systems that

have more than eight voice mail ports or when Record a Call is

frequently used.

4. The MX controller can support 12 LS/CLASS, 2 DNIC, and 4 ONS

on the internal analog boards in all option configurations.

5. All T1 trunk quantities include any combination of T1/D4 or

T1/PRI.

6. The maximum system capacity is 672 TDM (ONS/DNIC) ports. In

any option configuration, trunks may be added up to a maximum

of 8 digital links (192 trunks) but only by reducing the number of

digital bays (ONS and DNIC ports) connected, so that the total

number of TDM ports does not exceed that shown in the table.

7. If System Option 82 is enabled (DSP Echo Cancellers), then one

DSP device is removed from the available pool. The number of

TDM resources (voice mail and conference) will be reduced. This

option cannot be used in a base system with compression

enabled (Business Option 1) or with a large number of TDM

devices (Analog Options 1 and 2).
