Description

The FlexNetwork MSR 2-port E1 Voice HMIM Module adds digital TDM voice connectivity to HPE MSR multiservice routers. It connects the router to a PBX, the PSTN or a WAN over E1, making it well suited to branch and enterprise voice gateway deployments, PBX interconnect and TDM-to-IP gateway applications.

The module provides two E1 ports (G.703 physical layer, G.704 framing) with support for both PRI (ISDN) and CAS signalling, and handles up to 60 voice channels. A 64-channel voice processing module (VPM) is embedded, so no separate voice processing module is needed for the module's own channels. G.711 and G.729 voice codecs and fax are supported.

It is a full-height HMIM, occupying one full-height slot or two half-height slots in a host router. It works with the HPE MSR3000 series (MSR3012, MSR3024, MSR3044, MSR3064) and the MSR4000 series (MSR4060, MSR4080), and draws power from the host chassis backplane, so no separate power supply is required.

FAQs

Q: Which routers is this module compatible with?
A: It works with HPE MSR3000 series routers (MSR3012, MSR3024, MSR3044, MSR3064) and MSR4000 series routers (MSR4060, MSR4080) that have an HMIM slot.

Q: How much space does it take in the router?
A: It is a full-height HMIM, so it occupies one full-height slot or two half-height slots in the host router.

Q: Does it need a separate power supply?
A: No. The module is powered from the host MSR router chassis backplane.

Q: Do I need a separate voice processing module?
A: No. A 64-channel voice processing module (VPM) is already embedded, covering the module's 60 supported voice channels.

Q: Does it need a cable to connect to the E1 line?
A: On MSR4000 series routers an E1 cable is needed to connect the module to the E1 circuit.

Q: How does this module differ from other MSR voice modules?
A: This SKU is the 2-port E1 voice HMIM with both CAS and PRI signalling, designed for digital TDM trunk connections rather than analogue interfaces.
