G
A node configured to handle both T1 and E1 packet and circuit lines for direct interface international
gateway
circuits.
GCRA is a "continuous leaky-bucket" process that monitors the cell depth in the input queue for each
GCRA (Generic Cell
Rate Algorithm) PVC to determine whether to admit a new cell to the network without setting the Cell Loss Priority bit.
A frame relay addressing convention that uses the DLCI to identify a specific end device somewhere
global addressing
else in the frame relay network. In a global addressing scheme, the DLCI is a unique number for each
port in the network.
Frame relay connections grouping a number of ports onto one permanent virtual circuit. Similar to
grouped
connections bundled connections except the grouped connections do not have to be contiguous, nor do they all
have to be added simultaneously.
H
A line interface for E1, similar to B8ZS for T1, which eliminates patterns with eight or more
HDB3 (High Density
Bipolar Three) consecutive zeros. Allows for 64 Kbps clear channel operation and still assure the ones density
required on the E1 line.
An IGX front card that supports one to four medium speed, synchronous data channels.
HDP (High Speed
Data PAD)
I
A multi-service, multi-band ATM cell relay network switch for private and public networks.
IGX Switch
INS is the broad name for a range of products that enhance traditional Cisco WAN switching
Intelligent Network
Server (INS) networks. These products include Dial-Up Frame Relay, Voice Network Switching, and ATM
Switched Virtual Circuits.
Same as "Fast EIA".
interleaved EIA
A service provided by the telephone company or OCC that supports combined customer voice and
ISDN (Integrated
Services Digital data connections over the twisted pair subscriber loop. Requires special equipment at the customer

premise and a connecting central office switch that is capable of providing ISDN.
A narrowband cell relay network switch from for private and public networks.
IPX Switch
J
A. multiplexed 24-channel circuit line to a PBX conforming to the Japanese TTC-JJ-20 circuit
J1
standard. Similar to E1, it operates at 2.048 Mbps.
