Maximum run limited by baud
rate, typically:
less than 50 feet at 9.6 Kb/s
Maximum run without a repeater
is limited by baud rate, typically:
less than 4000 ft at 19.2 Kb/s
less than 1700 ft at 115.2 Kb/s
Maximum run without a router,
hub or repeater is limited by
baud rate, typically:
less than 333 feet at 1 Gb/s
This consists of 300 ft of 24
AWG solid "horizontal" cabling
between the jacks at each end,
plus not more than 33 ft of 24
AWG stranded patch cable
between each jack and the
CTM.

*2 pair twisted
TOLL PLAZA
* 2 pair twisted cable specified in the EIA RS232C,
CCITT V.55 and RS422 interface standards:
• Conductor size and type: 24 AWG, twisted pair.
• Nominal capacitance: 15.5 picofarads per foot
(between conductors of each pair); 27.5 picofarads
per foot (from each conductor to shield).
• Nominal DC resistance (each conductor): 24.0
ohms per 1000 feet.
• Nominal DC resistance (shield): 2.35 ohms per
1000 feet.
• Shield type: Overall braided with drain wire.
• Approval: Underwriters Laboratories (UL).
