1:1 Chassis Redundancy; Operating Modes - Motorola APEX1000 Installation And Operation Manual

1:1 Chassis Redundancy

Beginning with software release 2.3.8, the APEX1000 includes support for 1:1 physical
chassis redundancy. This is a broadcast redundancy scheme in which you may configure
a primary and a secondary APEX.
The Routing, OTS, and QAM Module configurations are synchronized between the two
APEXs. The primary and secondary APEXs communicate through heartbeat messages,
constantly informing each other about their configuration, role and operating state.

Operating Modes

The APEX1000 allows you to dynamically change a QAM channel's operational mode
without rebooting the unit; this avoids disturbing the other QAM channels on the QAM
Module.
The APEX1000 supports the following operating modes:
•
Session Controlled Mode — Indicates the mode of a given output, whereby
streams are routed to that output under the control of an external controller using
either the RTSP, MHA, or RPC protocols.
A QAM channel in Session Controlled mode can support a combination of SDV and
VOD streams. Furthermore, a Session Controlled QAM channel is either in RPC
Mode or RTSP Mode, as follows:
•
Manual Routing — In this mode, you configure the APEX1000 to manually route
and re-multiplex input MPEG services, transport streams, or PID streams to a
designated output QAM channel.
•
UDP Port Mapping — Denotes Legacy VOD mode.
•
M-CMTS DOCSIS Enabled — QAMs designated for this mode will be enabled to
receive a DOCSIS PID stream from an M-CMTS using D-MPT encapsulation. (PSP
L2TPv3 support will be offered in a future APEX1000 release.)
CAUTION The APEX1000 does not allow you to change the operating mode or PID remapping
mode of QAM output that has any active service or stream mappings. To perform these
modifications, you must first delete all service and stream mappings to that output.
