10/100BaseT - an ETHERNET configuration
that uses twisted pair wiring (typically
Cat 5 UTP unshielded twisted pair
cable with RJ45 8-pin connectors) to
transmit data up to 100 Mbps.
Binary Super Crosspoint Bus - similar to
super crosspoint bus, but the units dig-
its are allowed to cover the range of 0
to F, rather than 0-9 as in previous
switcher systems. Generated only by
the Jupiter, CE-2500, and BCS-3000
control systems.
Bus - in distribution switching, a channel
leading to an output or destination.
Example: “controls 20 buses” means
being able to select sources for 20 desti-
nations.
CPL - Control Point Language. Protocol
used to control router through Encore
/ SMS 7000 Ethernet connection. In
Trinix applications, the connection is
made to a NR-33000 Broadlinx board.
CPLD - Complex Programmable Logic
Device.
Crosspoint - distribution switcher circuit
where input signal can be connected to
output bus. A 10 x 10 crosspoint board
has 100 crosspoints.
Crosspoint Bus - Also called the matrix
bus. A five-pair bus that carries switch-
ing and status commands between the
crosspoint (matrix) cards and the con-
trol device.
The control device could be any one of
a large number of devices, including a
CE-300A Control Board (internal to
Mars), a SC-400 Control Board (inter-
nal to Venus), a CE-3000 Matrix Con-
troller (BCS-3000 control system), a CE-
2500 Control Electronics frame, a VM-
3000 Control Processor (Jupiter), or a
CE-2200 ( PARTY LINE system).
The protocol for this bus has changed
through the years to accommodate
larger and larger switchers with
increasing numbers of levels, being
identified as “standard,” “extended,”
“super,” and “binary.” For example,
the binary protocol uses binary (rather
than BCD) coding to increase maxi-
mum control size to 1024 x 1024 on 127
levels.
The “octal” protocol type is used only
for Mars switchers.
For additional information, refer to the
“Switcher Control Rulebook” appen-
dix of the Party Line Control Mainte-
nance Manual.
DHCP - Dynamic Host Configuration
Protocol. Provides automatic TCP/IP
configuration when a DHCP server is
present on the network.
DVB-ASI - Digital Video Broadcasting -
Asynchronous Serial Interface.
EBU - European Broadcasting Union.

Fabric Board - DM-33100 matrix board
used in Trinix router.
FPGA - Field Programmable Gate Array.
