E-10 Cisco BPX 8600 Series Reference
FTC (FastPAD Trunk Card)
An IPX frame relay front card that provides an interface to a FastPAD. The FTC is used with an
FPC backcard. that provides either a T1, E1, V.35, or X.21 interface.
FTM (FastPAD Trunk Module)
An IPX frame relay front card that provides an interface to a FastPAD.
G
gateway
A node that is configured to handle both T1 and E1 packet and circuit lines for direct interface
international circuits. (See also Seamless International IPX Network.)
GCRA (Generic Cell Rate Algorithm)
GCRA is a “continuous leaky-bucket” process that monitors the cell depth in the input queue for
each PVC to determine whether to admit a new cell to the network without setting the Cell Loss
Priority bit.
global addressing
A frame relay addressing convention that uses the DLCI to identify a specific end device
somewhere else in the frame relay network. In a global addressing scheme, the DLCI is a unique
number for each port in the network.
grouped connections
Frame relay connections grouping a number of ports onto one permanent virtual circuit. Similar
to bundled connections except the grouped connections do not have to be contiguous, nor do they
all have to be added simultaneously.
H
HDB3 (High Density Bipolar Three)
A new line interface for E1, similar to B8ZS for T1, which eliminates patterns with eight or more
consecutive zeros. Allows for 64 Kbps clear channel operation and still assure the ones density
required on the E1 line.
HDP (High Speed Data PAD)
An IGX front card that supports one to four medium speed, synchronous data channels.
I
IGX Switch
A multi-service, multi-band ATM cell relay network switch for private and public networks.
Intelligent Network Server (INS)
INS is the broad name for a range of products that enhance traditional Cisco WAN switching
networks. These products include Dial-Up Frame Relay, Voice Network Switching, and ATM
Switched Virtual Circuits.
interleaved EIA
Same as “Fast EIA”.
