            Ordering Information

            The Cisco High-Density Analog Service Module (SM-D-48FXS-E) for analog voice and fax devices is a doublewide voice and fax interface modules for Cisco 2951, 3925, 3925E, 3945, and 3945E Integrated Services Routers (ISRs). They enable packet voice technologies with support for Skinny Client Control Protocol (SCCP), H.323, Media Gateway Control Protocol (MGCP), and Session Initiation Protocol (SIP). These modules provide enterprises and managed service providers the ability to directly connect the public switched telephone network (PSTN) and existing telephony equipment to ISRs. With support for high-density analog ports, these modules are ideal for networks with high density voice and fax sessions requirements.

            The Cisco High-Density Analog Service Module provides gateway services for virtually any unified communications environments, including those that use Cisco Unified Communications Manager, Cisco Hosted Collaboration Solution (HCS), Cisco Unified Communications Manager Express, Cisco Business Edition, and even third-party IP private branch exchange (IP PBX) environments. Being integrated onto the Cisco ISR means that the network can operate at any point on the voice, video, and integrated data spectrum, with the ability to add connections for both analog telephony devices and IP telephony endpoints. Either topology environment will support business needs for a high concentration of analog voice ports for modem calls, fax calls, and analog supplementary services.
