Rtm Lan Card - Polycom RMX 2000 Hardware Manual

RealPresence Collaboration Server (RMX) 2000 Components and Components Replacement
.
Note: E1 and T1
E1 and T1 spans cannot be connected simultaneously to the same card, therefore, it is not possible
to have a mixed E1 and T1 ISDN Network Service
● Four 1Gb LAN ports:
Note: 200 audio participants
The RTM ISDN card supports 200 audio participants, regardless of whether the spans are E1 or T1.
● DBG port:
DBG port is an debug port for technician or field support use.
● ARM/CM switch:
ARM/CM is a switch for technician or field support use. The switch decides the output source
between CM or DSP UART for DBG port.

ISDN Clock Source
Each RTM ISDN card has its own primary and secondary clock source. The first span to synchronize
becomes the primary clock source and the second span to synchronize becomes the secondary clock
source. This clock is used to synchronize ISDN spans only (it is not the system clock).
A single clock source triggers an alarm that can be turned off by setting the appropriate flag in the system
configuration.

RTM LAN Card

Two RTM LAN cards are available as below:
●
RTM LAN card - four LAN ports
●
RTM LAN card - two LAN ports
RTM LAN card - four LAN ports
The RTM LAN card routes data between the MPMRx cards and components of the system, and sends
media by IP packets and provides connectivity to external IP networks.
Note: MPMRx card and RTM LAN card
An MPMRx card on the front of the RMX must always be seated or connected opposite to either an
RTM LAN card or RTM ISDN card on the rear of the chassis.
•
The four ports RTM LAN card is required on the RealPresence Collaboration Server (RMX) 2000 when
MPMRx cards are installed on the system. An RTM LAN card must connect directly to an MPMRx card. In
an RealPresence Collaboration Server (RMX) 2000 with a single MPMRx card, the RTM LAN card must be
installed in the rear panel slot at the top slot at the same level as the MPMRx card.
