CompactPCI High-Desity Trunk Interface
The NMS Convergence Generation™
(CG) 6100C Series provides high-density digital trunk
interfaces combined with digital signal processing
(DSP) resources for signaling and echo cancellation
on a CompactPCI (cPCI) board set (main board and rear
transition board). The CG 6100C offers rear panel
access for either 8 or 16 spans of E1 or T1. Some
configurations include a daughterboard with DSP resources
for more ports of IVR and fax. The CG 6100C is fully
H.110 (CT Bus) compliant to support switching of voice
paths with trunk boards or any H.110 timeslot. The
high-density of trunks saves valuable cPCI slots in
the large, high-availability environments of service
providers and carrier-class system applications such
as media servers, switches, wireless infrastructure,
and enhanced services platforms.
NMS provides developers with the widest
range of PCI and cPCI options — all under Natural
Access™, a unified program development environment
which provides a common API set to all Alliance Generation®
and Convergence Generation digital and analog board

Technical Description:
Natural
Access Program Development
The CG 6100C Series is supported using NMS' Natural
Access software development and runtime environment.
Natural Access provides a consistent set of APIs that
are operating system-independent, delivering application
portability. With Natural Access Call Control,™
programmers can easily and quickly develop applications
that run on multiple types of telecommunications interfaces
by using a single protocol-independent API. Natural
Call Control minimizes the processing overhead on
the host CPU by executing protocols on the board's
processor. Natural Access unifies application development
across NMS' Alliance Generation and Convergence Generation
products.
The CG 6100C handles the call control
on-board and interrupts the host CPU when an event
requires application action, minimizing host loading.
However, with a density of 480 DS0s per slot, call
activity can reach high levels when a number of CG
6100Cs are installed. Careful attention to loading
on the host CPU is required during application design.
H.110 Support
Assures Open Architecture, Vendor Independence
The CG 6100C Series provides full support of the ECTF
H.110 specification. The H.110 bus provides 4,096
timeslots operating at 8 MHz. The H.110 bus also allows
programmable operating speeds at 2, 4, or 8 MHz for
direct connection to existing boards at their native
operating speeds.
The CG 6100C Series uses the Lucent
Microelectronics Ambassador™ chip family that
offers full support for the H.100 bus within the MVIP
hierarchical architecture. It also provides an additional
1,024 timeslots of local on-board switching, improving
overall application efficiency and system scalability.
Dual Redundant
Ethernet
The CG 6100C features dual redundant 10/100 Base-T
Ethernet interfaces. These can be used either as two
independent subnets or in an automatic failover mode
that switches traffic to the alternate interface without
interruption of in-progress calls. This feature protects
against cut wires or hub failure.
Diagnostics
In addition to diagnostics run at boot-up time, the
CG 6100C performs run-time diagnostics for the following
events:
- Rear Transition Board Missing: If
the CG 6100C senses that the rear transition board
is not properly inserted, thus interrupting the
trunk paths, it will alarm the application.
- Temperature Measurements: The application
can request current temperature from sensors placed
on the board.
