Wire Gauge, Grounding, and Pairing
•Use 28 AWG
•The chassis must be grounded both by a drain wire and by the braid; both must be connected to the connector case and shell at each end of the cable. The braid must be connected through its full circumference.
•Wires identified under the heading ‘Twisted Pairs’ must be paired. If you do not install twisted pairs correctly, the cable will not work.
Type of Connectors
The VHSI port accepts a high density
•V.35: Type M
•V.24: DB25
