    You can use a CM-30 module in place of, but not at the same time as, a T1 or E1 common module (CM-3, CM-5, CM-5RB, CM-6, CM-7, or CM-7RB) in an existing Intraplex T1 or E1 multiplexer. You can then revert back to T1 or E1 at a later date by simply removing the CM-30 module and reinserting the original common module.

    2.1.6 IGMP Multicast The NetXpress LX system (or the CM-30 module in an original Intraplex system) interoperates with multicast routers using the Internet Group Management Protocol (IGMP). The IGMP Multicast mode involves transmission to specific hosts through IGMP routers. This scheme allows you to route specific packets onto specific segments, thereby segregating unwanted traffic from narrow segments.

    It supports the proprietary IGMP statistics MIB to account for all incoming and outgoing messages. 2.2 Streams Within the NetXpress LX multiplexer or an original Intraplex multiplexer, the CM-30 IP interface module uses packet streaming to transport audio signals. 2.2.1 Stream Types 2.2.1.1...

    2.2.3 Multicast Group Addressing The CM-30 IP interface module, within the NetXpress LX system or an original Intraplex system, supports multicast use for stream transmission and supports creating up to 32 transmit, receive, or a combination of transmit and receive streams. This system does not make any restrictions on the type of multicast address used for a stream destination.

    The NetXpress LX system can provide echo cancellation for voice circuits using up to 2 optional echo canceller cards that plug onto the CM-30 module. Each board can provide echo cancellation for up to 30 channels per echo canceller card on the TDM bus.

    2.5.3 TDM Bus Mapping The NetXpress LX or CM-30 TDM bus is connected by default to a virtual IP bus; this connection is bi- directional. The TDM bus mapping feature allows you to reconfigure your connections to suit your needs. You can connect a time slot from TDM A, TDM B, or either of the echo cancellers to the corresponding time slot on any of the 4 IP ports.

    2.7.1.1 Internal Timing Internal timing is derived from an extremely accurate internal oscillator on the CM-30 module. In a NetXpress LX network, only the master NetXpress LX system can use internal timing. Other NetXpress LX shelves in the network must use external, stream, or SynchroCast timing derived from the network master.

When a subordinate system derives timing from the master, clock recovery algorithms are employed to align clock frequency and control packet jitter/wander. Also, in order to recover timing from a stream, the stream must be active and sending.
