2.4.1.1.1 Connecting Dialogic D/240SC-T1 and DTI/211 T-1 Modules
On the rear bracket of the D/240SC-T1 and DTI/211 network modules is an RJ-48C jack for
connecting to the T-1 network. The cabling between this jack and the CSU or other DSX-1
equipment should be 4-pair telephone line or equivalent. The network interface module of the
cable should consist of an RJ-48C plug. The user is responsible for supplying an appropriate
cable for these connections. The pin designations for the network interface module cable end
for D/240SC-T1 modules are specified in Table 2-1.
