Terminator Boards are plugged onto the appropriate
Backplane connectors at the factory. No changes to these
boards should be required at installation.
❏
Verify each Terminator Board has not become
loose during shipment. Each Backplane should
have one Terminator Board plugged to connectors
P1E2 and P2E2 (located on the far left-hand side of
Backplane as viewed from the rear) and a second
Terminator Board plugged to connectors P1E1 and
P2E1 (located on the far right-hand side).
CONCENTRATOR CARD CABLES
Each Concentrator Card Cable in the Compact CEC
cabinet interconnects a 24-pin dual-row connector on the
rear of the Backplane to a similar type connector on a
Concentrator Card. Twisted-pair shielded cabling is utilized
on all of these factory-installed cables.
❏
During the installation process, no Concentrator
Card Cable changes should be required. Simply
verify none of the cables have become loose during
shipment and they are all connected in accordance
with Figures 5 thru 9 in this manual.
UPLINK GETC CABLES
❏
As shown in Figure 5 in this manual and in the
Application Assembly Diagram in LBI-39116,
verify cable 19D903628P41 interconnects PA201
on Card Cage 1 to J100 on the back of the GETC.
PA201 is a 24-pin dual-row header connector on
the Backplane and J100 is a DB-9 subminiature
connector. Also verify cable 188D6159P1
interconnects the GETC, Data Concentrator Card
A2 and the RPS unit.
EXTERNAL CONNECTIONS
Punch Blocks
As previously stated, three (3) punch blocks within the
Compact CEC cabinet are mounted on a punch block
mounting rack. These punch blocks provide the audio and
control data interconnect points for the external equipment
such as the C3 Maestro consoles and the EDACS trunked
site. The mounting rack is secured to the cabinet's rear
horizontal mounting rails just above the RPS unit. If
required, this punch block assembly may be relocated
outside of the Compact CEC cabinet. The five (5) factory-
supplied Telco cables which interconnect the Compact
CEC's Concentrator Cards to the punch blocks are 15 feet
(4.57 meters) in length. If longer or shorter Telco cables are
required, see Table 1 for part number information.
❏
At this time, refer to the punch block pin-out
diagrams at the end of this manual. Wire all
external equipment to the Compact CEC's punch
blocks as required.
NOTE
Bridging clips may be supplied with the C3
Advantage's punch blocks; however, the bridging
clips
should not
be used.

External Cable Length And Shielding
Audio
Maximum audio line length is limited only by the line
loss and induced noise. All audio lines should employ 600-
ohm twisted-pairs or equivalent microwave links.
Local audio lines should not require shielded pairs
unless noise is a problem. Shielded pairs are recommended
for all local lines that carry modem signals. A pre-wired
100-foot shielded audio cable is supplied with each C3
Maestro console for console-to-CIM line audio
interconnections.
RS-232/RS-422 Control Data
RS-232 interfaces should be limited to 50 feet (15.24
meters) and RS-422 interfaces should be limited to 4000 feet
(1219 meters). These length specifcations include Telco and
Concentrator Card cabling. A pre-wired 100-foot RS-422
data cable is supplied with each C3 Maestro console for
console-to-CIM control data interconnections.
