Ethernet interface specifications
The APX 1000 Ethernet interfaces support the physical specifications of
IEEE l802.3 with Ethernet 2 (Ethernet/DIX) framing.
Supported Ethernet types
APX 1000 units can support any of the following Ethernet interface types:
•
10BaseT (unshielded twisted pair): Twisted-pair Ethernet and IEEE 802.3 (10BaseT) with
an RJ-45 connector
•
100BaseT (unshielded twisted pair): Twisted-pair Ethernet and IEEE 802.3u
(100BaseT) with an RJ-45 connector
Required equipment for 10BaseT or 100BaseT
To install an Ethernet interface, you must have the appropriate equipment for the type of
interface to be installed.
For a 10BaseT or 100BaseT connection, you need a twisted-pair Ethernet cable terminated
with RJ-45 modular jacks.
Use an EIA/TIA 568 or IEEE 802.3 10BaseT cable. Some installations require a crossover
cable (for example, when connecting directly to the Ethernet port of a PC).
T1/PRI interface specifications
Specifications for an APX 1000 unit’s T1/PRI interface include channel service unit (CSU)
and digital signal cross connect (DSX) requirements, specifications for the cables and the
plugs available for the unit’s WAN interfaces, the pins to be used on the WAN ports, and the
WAN switched services that are available to the APX 1000 unit.
T1/PRI CSU and DSX specifications
All APX, TNT, and MAX T1 cards are equipped with internal CSU and DSX hardware. No
additional hardware is required.
An APX 1000 unit’s internal CSUs are compatible with wet-loop and dry-loop T1/PRI lines
and with span-powered or wet-loop-powered T1/PRI lines. Your telephone carrier provides the
correct value for the line buildout setting for CSU connection, or line length for DSX
connection. You configure these parameters during installation. (For more information, see the
APX 8000™/MAX TNT® Reference.)
Once you install the APX 1000 unit, you must notify the carrier before disconnecting the unit
from the WAN. If you disconnect or turn off the unit without prior notification, the carrier
might temporarily discontinue your T1/PRI service.
