RJ-45 to DB15F Cable Assembly (For T1/E1 Port 120
Ω Connections)
The following parts are recommended for the ends of the cable:
• For the switch side of the cable assembly (P1): 8-conductor RJ-45 round connector 
(MTP-88U or equivalent)
• Parts for the customer end of the cable (P2) can be of any industry-standard manu-
facturer. Use of a shielded-type DB-15 female connector is recommended.
Cable should be constructed with datacomm-quality cable that has an overall mylar 
foil shield and braided-shield, terminated to the appropriate pins and connector shell 
at each end of the cable. Twisted-pair 28GA cable is preferred, with any of the pairs 
used for non-paired signals.
