## Long description

AUDIOCODES Mediant 500L MSBR 4 BRI ADSL VDSL is a compact VoIP gateway that provides SIP-based voice interworking between IP networks and ISDN BRI interfaces while supporting ADSL and VDSL copper access. Designed for small and medium deployments, the device enables organizations to keep existing telephony equipment connected to legacy BRI lines during migration to IP telephony. The gateway integrates voice protocol conversion, signaling interworking and media handling to allow smooth operation with SIP-based service providers and on-premises PBX systems.
Advantages
The Mediant 500L MSBR consolidates multiple functions in a single chassis: ISDN BRI termination, SIP trunking and ADSL/VDSL access support. It reduces complexity by providing protocol interworking and media adaptation between packet networks and circuit-switched BRI lines. The platform is optimized for deployments where preservation of existing copper interfaces and telephony endpoints is required, and it is suitable for mounting in limited-space installations. Device capabilities include robust SIP interoperability and voice quality mechanisms to ensure reliable call delivery.
Suitable for
 Connecting legacy PBX or ISDN handsets to SIP-based service providers
 Small and medium branch offices requiring continued use of BRI lines
 Migrations from copper-based telephony to IP while retaining existing hardware
 Sites with ADSL or VDSL copper broadband access
Key specifications
 Interfaces: 4 ISDN BRI ports for NT/TE connectivity
 WAN access: ADSL and VDSL support for copper broadband links
 Protocol support: SIP for VoIP signaling and ISDN/B channel handling
 Media features: RTP/RTCP media handling, codec support for standard voice codecs
 Deployment: compact form factor for small/branch office installations
 Quality mechanisms: echo cancellation and jitter management for stable voice quality
How to use
Install the Mediant 500L MSBR in a secure network location with access to the copper WAN line and the local PBX or ISDN endpoints. Connect the ISDN BRI ports to the existing telephony equipment and the ADSL/VDSL port to the service provider’s copper line. Configure SIP trunk settings and call routing parameters through the device management interface, ensuring correct mapping between BRI channels and SIP dial plans. Apply appropriate network settings such as VLANs, QoS and NAT traversal options according to the site network design. Test call flows in both directions and verify codec negotiation and D-channel signaling for each BRI circuit.
Usage recommendations
 For reliable operation, keep the device firmware up to date and coordinate SIP interworking settings with the IP service provider. Use Quality of Service (QoS) on the access network to prioritise voice traffic, and validate ADSL/VDSL line quality if intermittent issues are observed. When migrating large numbers of users, plan gradual cutovers to confirm interoperability with on-premises PBX features and ISDN supplementary services.
