To use an IEEE 802.3 or Ethernet interface (thick-wire, thin-wire, or unshielded twisted-pair) at
your installation, you need an 802.3 media attachment unit (MAU) and an attachment unit
interface (AUI), or an Ethernet transceiver and transceiver cable. The AUI or transceiver cable
will need an AUI 15-pin plug to connect to the 15-pin AUI receptacle on the EIP. Some interface
equipment may use cables with screw-type locks rather than the slide-type locks that are standard
on the EIP. A kit for replacing the slide-type locks with screw-type locks is shipped with the EIP.
•
For IEEE 802.3u Fast Ethernet (100BaseT) connections to the FEIP, you need Category 5, UTP
cable for RJ-45 connections or Media Independent Interface (MII) cables for MII connections.
For more detailed Fast Ethernet cable requirements, refer to the section "Fast Ethernet
Connection Equipment" in this chapter
Caution
Before you attach an MII transceiver to an MII receptacle on your FEIP, ensure that your
MII transceiver responds to physical sublayer (PHY) address 0 per section 22.2.4.4. "PHY Address"
of the IEEE 802.3u specification; otherwise, interface problems might result. Confirm that this
capability is available on your MII transceiver with the transceiver's vendor or in the transceiver's
documentation. If a selection for "Isolation Mode" is available, we recommend you use this setting
(if no mention is made of "PHY addressing").
•
To connect a 4- or 16-Mbps Token Ring interface, you need an 802.5 MAU and a Token Ring
adapter cable.
•
To use the optical bypass feature available with multimode/multimode FDDI interfaces, you need
an optical bypass switch. A DIN-to-mini-DIN control cable (CAB-FMDD) for connecting the
switch is included with the multimode/multimode and single-mode/single-mode FIPs.
•
To use a low-speed synchronous serial interface, you need a synchronous modem or a (CSU/DSU
to connect to the network. Most modems require an EIA/TIA-232 DTE connection.
•
To connect serial adapter cables to remote devices that use metric hardware, replace the factory
installed 4-40 thumbscrews on the cable's network-end connector with the M3 metric
thumbscrews that are included with all serial port adapter cables.
•
To connect a serial port to a T1 network, you need a T1 CSU/DSU that converts the High-Level
Data Link Control (HDLC) synchronous serial data stream into a T1 data stream with the correct
framing and ones density. (The term ones density refers to the fact that some telephone systems
require a minimum number of 1 bits per time unit in a data stream). Several T1 CSU/DSU devices
are available as additional equipment and most provide either a V.35, EIA/TIA-449, or EIA-530
electrical interface to the system.
T1 is the term for a digital carrier facility used for transmitting data over a telephone network at
1.554 Mbps. E1 is the European equivalent of T1 and has a line rate of 2.048 Mbps.
•
To connect a HSSI port, you need a DSU that can process data at speeds appropriate for the
service to which you will connect: T3 (45 Mbps), E3 (34 Mbps), or SONET STS-1
(51.84 Mbps). In addition, you need a HSSI interface cable (CAB-HSI1) to connect the DSU
with the HIP.
T3, also known as DS3 or digital signal level 3, is the U.S. standard for a digital carrier facility
used for transmitting data over a telephone network at 44.736 Mbps. T3 is equivalent to 28 T1
(1.544 Mbps) interfaces. E3 is the European equivalent of T3 that operates at 34 Mbps.
