Embedded Data Link Connection Identifier. Use when multiplexing user data on a single
DLCI (comparable to having multiple DLCIs on an interface being routed to a single DLCI
on the network side). EDLCIs use a proprietary method to multiplex DLCIs that have been
selected as one end of a connection. An EDLCI is a number between 0 and 62, and it
identifies the individual connection within a multiplexed DLCI.
An excessive bipolar violation condition results when at least one invalid bipolar violation
has occurred every 20 milliseconds for 2 seconds. A Health and Status message (under
the Status branch/menu) is generated when this condition is detected.
One identifiable group of bits that includes a sequence of bits for control, framing, etc.
A switching interface that is designed to get frames from one part of the network to another
as quickly as possible.
Frame Relay Aware. Means the access unit can read the frame relay header and route the
data internally to the correct port. This function allows an access unit using RFC1490 to
distinguish its address on an incoming IP packet, and determine that the packet is for the
access unit.
Internet Protocol. The TCP/IP standard protocol that defines the IP as a unit of information
passed across an Internet and provides the basis for packet delivery service. IP includes
the ICMP control and error message protocol as an integral part. The entire protocol suite
is often referred to as TCP/IP because TCP and IP are the two most fundamental
protocols.
Integrated Services Digital Network. Telecommunication service that uses digital
transmission and switching technology to provide voice and digital data communications
on a bearer (B) channel while sending signaling on the data (D) channel.
Light Emitting Diode. A light or status indicator that glows in response to the presence of a
certain condition (e.g., ALM on the front panel for an alarm condition ).
Local Management Interface. The standard set of procedures and messages that manage
PVCs – the route between two DTEs. It is a common standard for link-management
signaling (information exchange).
Network Access Module. It is a type of CCA that accesses or interfaces with the network.
Network Management System. A computer system used for monitoring and controlling
network devices.
A designated port, DLCI, and EDLCI for the primary data path from the data source so a
PVC connection can be established.
The rules for timing, format, error control, and flow control during data transmission.
Permanent Virtual Circuit. This is the DSU's in-band management channel that supports
remote management via a Telnet connection. It is the logical link, identified by a DLCI,
used for routing frames over the network from their source to their destination.
Routing Information Protocol. Specifies the routing protocol used between access units.
Simple Network Management Protocol. A generic network management system that
allows the device to be managed by any industry-standard SNMP manager.
Data with an accompanying time signal.
Virtual terminal protocol in the Internet suite of protocols. Allows the user of one host
computer to log into a remote host computer, and to interact as a normal terminal user for
that host.
Test Mode. An EIA-lead standard for V.24 circuit TM, ITU 142; an output signal
( DCE-to-DTE ).
