Receiver Provisioning

This section provides receiver requirements for DTMF and CLASS receivers. DTMF receivers
are a shared system resource with provisioning done on a system level. CLASS receivers are
dedicated to the modules on their associated SX-200 SPINE.
The MCC contains seven receivers which can be programmed as DTMF receivers or as DSP
circuits in System Option 68, DSP DTMF Receiver Channels (0...7 default = 7) to optimize
performance.
Seven SX-200 SPINE CLASS/DTMF receivers can be allocated as CLASS or DTMF, with a
maximum of five CLASS receivers (default is three CLASS and four DTMF). System Options
61-67 can be selected to optimize performance based on the proportions of ONS to LS/CLASS
modules in each SX-200 SPINE Bay.
DTMF receivers can also be provided by adding DTMF Receiver/Relay modules to a Universal
Card. Each module contains four DTMF receivers.
Calculate receiver provisioning requirements for an SX-200 EL or SX-200 ML system using
the following table.
Step
1. Calculate the total number of ports that
may require access to a DTMF receiver.
Ports include:
• analog DID trunks
• digital DID trunks
• digital E&M trunks
• ONS ports
• OPS ports
• COV ports
