22 Enterasys X-Pedition 8000/8600 Getting Started Guide
Options Available
This module operates with the following APHYs (you may purchase them separately from the
module) connected to the outside world. For information about these APHYs, consult the Enterasys
Networks web site.
Caution: The X-Pedition-APHY-21 and X-Pedition-APHY-29IR use Class 1 Lasers. Do not use
optical instruments to view laser output. The use of optical instruments to view laser output
increases eye hazard.
Note: Before you can remove an APHY, Hot Swap the host ATM module.
The ATM line card has two available slots. Each slot accepts the following PHY interface modules:
Port type Specification
APHY-67 • 1 DS-3/T-3 interface (BNC Coax); see APHY-67 and APHY-77
on page 81 for attaching cables
• 75 coaxial (RG-59B or equivalent) terminated with 75-ohm BNC
connectors
• Maximum of 450 ft (137 m) of cable
APHY-77 • 1 E-3 interface (BNC); see APHY-67 and APHY-77 on page81
for attaching cables
• 75 coaxial (RG-59B or equivalent) terminated with 75-ohm BNC
connectors
• Maximum of 450 ft (137 m) of cable
APHY-82V • 1 T-1 interface (UTP); see APHY-82V on page81 for attaching
cables
Note: The APHY-82V is not a T1 interface. It merely allows you
to connect to a T1 CSU—the T1 CSU will allow you to
connect to a T1 circuit.
• ITU-T G.703 for a symmetrical pair
• 100 ohm symmetrical pair
• Maximum of 655 ft (200 m) of cable
• 0 through 6 dB loss at 200 m
