Distribution Panels and Cables
Distribution panels are used with 16-port T1/E1 ASAP Adapter cards to connect to T1/E1
circuits, and with 12-port Serial Data Interface cards to connect to V.35 or RS-232 circuits.
There are three distribution panels that are used with the T1/E1 ASAP Adapter cards:
•BNC
• mini-coaxial
•RJ-45
The 12-port Serial Data Interface card is connected to either a V.35 or RS-232 distribution
panel or to a customer-supplied distribution panel.
BNC Distribution Panel
Figure 10 shows the BNC Distribution panel. Table 3 lists the panel features.
The BNC panel provides 75-ohm E1 access for up to 32 ports. On the customer side, each
access port has separate transmit and receive BNC female connectors. On the equipment
side, the panel has two sets of 68-pin AMP connectors for connection to two 16-port T1/E1
ASAP cards via 68-pin AMP to 68-pin AMP T1/E1 cables (see T1/E1 Cables on page 57).
One set of AMP connectors on the panel is for network ports 1 to 16, and the other set is for
network ports 17 to 32.
Note: The connector on the faceplate of the 16-port T1/E1 ASAP Adapter card is a 68-pin
AMP connector that is typically associated with SCSI-2 interfaces. Although the connector is
sometimes referred to as a SCSI-2 connector, this document refers to it as a 68-pin AMP
connector. This naming convention applies to the connector on any T1/E1 cable that
attaches to the 16-port T1/E1 ASAP Adapter card.
Note: A set of connectors consists of one MAIN connector and one SPARE connector. When
connecting to 16-port T1/E1 ASAP Adapter cards, always use the (bottom) connectors
labeled MAIN.
