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 digits 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: “con-
trols 20 buses” means being able to select sources for 20 destinations.
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 switching and status
commands between the crosspoint (matrix) cards and the control device.
The control device could be any one of a large number of devices, including a CE-300A Con-
trol Board (internal to Mars), a SC-400 Control Board (internal to Venus), a CE-3000 Matrix
Controller (BCS-3000 control system), a CE-2500 Control Electronics chassis, a VM-3000 Con-
trol 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) cod-
ing to increase maximum control size to 1024 x 1024 on 127 levels.
The “octal” protocol type is used only for Mars switchers.

Line Control Maintenance Manual, Grass Valley part no. 04-043473-010.
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.
