Cabling D/240PCI-T1 Linecards to the Telephone System
With the D/240PCI-T1 linecard(s) installed in the platform, you can now cable the
platform to the telephone system. As described in “Assigning the Linecard Identification
Number,”
OneBox assigns line numbers in ascending order based on the linecard
identification number. For example, a D/240PCI-T1 linecard to which you assigned
linecard ID 1 will be assigned line numbers 1–24; a D/240PCI-T1 linecard to which you
assigned linecard ID 2 will be assigned line numbers 25–48 (as shown in Figure 11).
Keep this line number assignment scheme in mind when connecting each D/240PCI –T1
linecard to the telephone system.

This section describes the basic equipment for implementing T-1 and how to connect this
equipment to a D/240PCI-T1 linecard. The equipment needed for a T-1 installation is
shown in Figure 12 and explained in the following paragraphs.
