Cisco BPX 8600 Series Installation and Configuration
Release 9.3.30, Part Number 78-12907-01 Rev. E0, May 2005
CGA
carrier group alarm.
A major alarm condition for a T1 multiplexer or PABX that results in all channels being taken out of
service.
channel
The logical end point for a connection.
channel associated
signaling
See
CAS.
circuit line
A T1 or E1 line that connects a user device, such as a PABX or channel bank to a switch. Carries
customer DS0 voice and data circuits.
See also
line.
Cisco WAN
Manager
A UNIX-based workstation and software used as a network management system (NMS) for Cisco
WAN switching networks. Provides a graphical user interface for configuration, maintenance,
administration of the network. Collects and displays network statistics.
class of service
See
CoS.
clear channel
capability
When all eight bits of a channel word in the T1 line signal are available for transmitting customer data
with no restrictions on content. Also referred to as 64 Kbps clear channel.
CLI
command line interface.
There are two separate Command-Line Interfaces on the BPX-LSR: One on the BPX itself and one on
the MPLS (Multiprotocol Label Switching) Controller. The Control Point integrate these into a single
command line interface.
CLLM
consolidated link layer management.
A protocol used to transmit ForeSight messages across the frame relay NNI port.
CLP
cell loss priority.
CLP Hi and CLP Lo thresholds are configured.
Cmax
A frame relay connection parameter that specifies the number of packets allowed in the initial burst of
data after which the data bandwidth is reduced to the connection's minimum specified bandwidth.
command line
interface
See
CLI.
CommBus
The CommBus is the BPX internal messaging protocol. The Switch Control Interface (SCI) that is used
by PNNI on the Service Expansion Shelf (SES) is based on CommBus messaging accessed through
interfaces to the BPX cards.
common channel
signaling
See
CCS.
Complex Gateway
Refers to interworking of a connection with respect to the IGX nodes. For example, in a Frame Relay
to ATM interworking, the Frame Relay data is extracted from FastPackets and transformed to ATM
cells with redundant overhead bits discarded.
compliant cell
delay variation
See
CCDV.
composite data
rate
The sum of the data rates for all circuits transmitting on the same synchronous or frame relay data card.
