Ethernet interface specifications
The base unit of a MultiVoice Gateway has an Ethernet interface that supports the physical
specifications of IEEE 802.3 and IEEE 802.14 with Ethernet 2 (Ethernet/DIX) framing. The
unit provides a single Ethernet interface that auto-senses the Ethernet type to which it is
connected. It supports the following types:
•
10Base-T (Unshielded Twisted Pair): Twisted pair Ethernet and IEEE 802.3 (10Base-T)
with an RJ-45 connector, labeled LAN UTP.
•
100 Base-T: 100 Mbps Baseband Modulation on Twisted Pair.
•
AUI (Attachment Unit Interface): Standard Ethernet and IEEE (10Base-5) with a 15-pin
AUI connector (MAX 4000/MAX 2000).
The Ethernet address used to identify the Ethernet interface resides in the MultiVoice Gateway
unit’s motherboard.
To install the Ethernet interface, you must have the equipment described in either of the
following sections.
10Base-T
For 10Base-T, you need a twisted-pair Ethernet cable and a dual twisted-pair cable terminated
with RJ-45 modular jacks.
Use an EIA/TIA 568 or IEEE 802.3 10Base-T cable.
100Base-T
For 100Base-T, you need a twisted-pair Ethernet cable and a dual twisted-pair cable terminated
with RJ-45 modular jacks.
Use one of the following cables: 100BASE-T2, 100BASE-T4 (not very popular),
100BASE-TX, or 100BASE-FX.
AUI
For Standard Ethernet, you need a transceiver and transceiver cable.
