2WFXS-RTM Use Case
SMB PBX Expansion with 2WFXS-RTM-CTP2000 for Scalable Analog Extensions
A mid-sized enterprise is upgrading its legacy PBX system to support additional analog receptionist and fax lines. By installing the 2WFXS-RTM-CTP2000 rear transition module into the existing CTP2000 chassis, the IT team adds two new FXS ports in under 15 minutes without rewiring. Outcome: rapid analog port scaling, zero disruption to live voice traffic, and a 30% infrastructure cost saving compared to purchasing a new PBX.
Remote Office Analog Line Integration over MPLS Using 2WFXS-RTM-CTP2000
A regional bank deploys remote kiosks that require local analog dial-in security systems. The network operations center leverages the 2WFXS-RTM-CTP2000 module on the CTP2000 VoIP gateway to bridge analog FXS devices over the MPLS backbone. Outcome: secure, low-latency analog device connectivity, centralized management via SIP trunks, and a 40% reduction in field maintenance visits.
Call Center Business Continuity with Redundant Analog Backup on CTP2000
A 100-seat call center mandates uninterrupted customer support during IP network outages. Integrating the 2WFXS-RTM-CTP2000 into their CTP2000 chassis provides two dedicated analog FXS ports for failover to PSTN. Outcome: seamless continuity of inbound/outbound calls, zero SLA penalties, and improved customer satisfaction scores during planned or unplanned IP disruptions.
