Information to collect
Identify the line role and signaling before selecting a router voice module.
Provide the current host PID, software version, required interfaces and installation constraints before choosing replacements.
Selection checks
- NIM-2FXO and NIM-4FXO provide FXO analog interfaces; they are not FXS subscriber ports.
- NIM-2MFT-T1/E1, NIM-4MFT-T1/E1 and NIM-2CE1T1-PRI require checking the exact digital interface and operating role.
- Voice service also depends on supported host software, DSP or PVDM resources, codecs and entitlements. Port count alone does not prove call capacity.
Before deployment
- Test inbound and outbound calls, signaling and caller identification as required.
- Exercise concurrent calls, fax or other contracted services.
- Record line settings, DSP resources, software and acceptance results.
Preparing a quotation request
Include the exact part numbers, quantities, required condition, included accessories and software entitlements. Identify the target equipment and any unresolved interface or configuration item. A product association is not a validated combination.
