CID61
The CID61 port processor (Part # (Part #030005-006) is designed to function as a high-
speed WAN or legacy interface port processor, and TDM buses. The CID61 port processor
is capable of a single V.35 or three RS232 ports. An optional DSU module may be added
to the CID61 port processor to perform a 56/64Kbps DDS WAN connection. The CID61’s
access to the four TDM buses has various uses, the most common being a combination with
a DTC11 port processor for an FT1/T1 interface to the WAN. The CID61 port processor
also acts a carrier for the DVF18 voice compression module for packetized voice. Other
uses include subrate or channelized legacy protocol termination and clear channel muxing
of applications such as video.
A typical application would be the CID61 port processor configured as a Frame Relay WAN
port receiving LAN data from the high-speed bus, and legacy data from the standard bus.
The CID61 port processor places the data in a frame relay packet and transmits the packet
over the TDM bus to the DTC11/T1 port processor located within the same chassis.
Note: The RS232 and V.35 formats use the same DB25 port on the IEN 2000, IEN 3000, IEN 4000,
and IEN 5000 chassis, and are selected by jumpers JT11-20. RS232 or V.35 must also be
properly selected in the IENView port configuration.
Figure 3-7 illustrates the bus communications for the CID61 port processor.
