About this Guide
This guide describes methods and procedures for troubleshooting the Residential Cable VoIP (RCVoIP)
implementation of the Cisco Broadband Local Integrated Service Solution (BLISS) Release 1.5 on
broadband networks with the focus on the Cisco equipment used in the solution. It also provides
additional information on some of the technology issues related to VoIP over a cable network.
This document covers troubleshooting guidelines specific to the cable access portion of the network,
the PSTN interconnect portion of the network, and the Cisco BTS 10200 Softswitch node.
Audience
This document is intended to be used by Cisco Customer Support Engineers, service provider personnel
involved with operating and troubleshooting the solution, and anyone else who might be responsible for
troubleshooting an RCVoIP network.
The audience for this document is assumed to have a thorough knowledge of the following areas:
• UNIX commands and operation of the Cisco BTS10200 Softswitch
• Provisioning the Cisco BTS10200 Softswitch for trunk-side and line-side services
• Configuring the Cisco MGX8850 voice gateway for connectivity to the PSTN
• Configuring the Cisco uBR7246vxr/uBR10012 for connectivity to the cable headend
• SS7, MGCP, NCS, and DQoS signaling protocols
• DOCSIS™ 1.1, PacketCable™ 1.0 specifications
References to related documentation are supplied in this preface and in each chapter of the guide.
Assumptions
The BLISS for Cable Release 1.5 solution is deployable as either a primary line or secondary line
residential voice solution, dependent on the whether the service provider chooses to install line-powered
MTAs. BLISS for Cable Release 1.5 supports the G.711 CODEC, with other CODECs and CODEC
negotiation planned for a later release. Not all MTAs support 3-way calling, so that feature also depends
on which MTAs the service provider chooses to install. BLV/OI is not supported in this release.
The BLISS for Cable Release 1.5 solution adheres to the following PacketCable™ specifications:
• PacketCable™ Dynamic Quality of Service (DqoS) Specification, PKT-SP-DQOS-I03-020116
• PacketCable™ Security Specification, PKT-SP-SEC-I05-020116
