Terminal block requirements
The cross-connect terminal requires enough connecting blocks to terminate
up to four 25 pair cables for each Media Gateway and each Media Gateway
Expander. When Ethernet connections are used instead of traditional cabling,
the Media Card Input/Output adapter is used:
• For the 1.5 Mbit DTI/PRI circuit card NTRB21, use the NTBK04 cable.
• For the 2.0 Mbit DTI circuit card NTAK10, 2.0 Mbit PRI circuit card
NTAK79, and 2.0 Mbit PRI circuit card NTBK50, use the NTBK05
cable.
• Each IPE card slot equipped with a Line or Trunk card requires a 25-pair
cable from the host Media Gateway or Media Gateway Expander.
• Four conductors for the AUX cable from the Media Gateway.
• One 25-pair cable from each Power Fail Transfer Unit (PFTU) QUA6.
• Wiring from telephones and trunks
