For E1, the connections and signal designations are exactly the same, except that each span
handles 30 separate lines under the E1 transmission protocol. The DCC is dedicated to either a T1
or E1 interface, so the DCC installed in the system depends on the local PSTN standard.
Note:
The terms tip and ring are telephone terms that originated when loop circuit connections were
manually made with phone plugs (that is, tip is positive and ring is the return).
RJ48M Crossover Cable
For loop-back or other offline tests where outbound spans are looped back directly to inbound
spans, a special crossover cable can be fabricated. On a crossover cable, the transmit pins of each
span on one connector are connected to the receive pins for that span on the other connector. For
example, the connections for span 1, are made as shown in the following illustration. The same
order applies to the remaining spans.

RJ48C

Systems that are equipped with a TCCP with RJ48C connectors provide separate connectors for
each PSTN span. See
the RJ48C plug and pin-outs used to connect a single span (T1 or E1).
RJ48C Direct Feed Pin Outs
A standard direct feed cable with RJ48C connectors is connected at both ends in accordance with
the following table. Each pin of either connector is connected to the corresponding pin of the other.
