Ethernet interface specifications

The MAX TNT Ethernet interfaces support the physical specifications of IEEE l802.3 with Ethernet 2 (Ethernet/DIX) framing. It can support any one of the following Ethernet types:

Required equipment

To install the Ethernet interface, you must have the equipment described in the sections below.

Coax

For a coax connection, you need a BNC T-connector. If your connection is at the end of a cable segment, you need a 50-ohm terminator as well.

To install, attach a LAN BNC T-connector to the BNC port on the back of the MAX TNT. Use a standard 10Base-250-ohm cable, such as RG-58 A/U or RG-58 C/U.

Breaking the LAN's continuity, by inserting a cable segment or removing either of the 50-ohm terminations, disrupts and disables the Ethernet.

10Base-T/100Base-T

For a 10Base-T or 100Base-T connection, you need a twisted-pair Ethernet cable terminated with RJ-45 modular jacks.

Use an EIA/TIA 568 or IEEE 802.3 10Base-T cable. Some installations require a crossover cable (for example, when connecting directly to the Ethernet port of a PC).

AUI

For an AUI interface, you need the appropriate transceiver and transceiver cable.

T1/PRI interface specifications

This section provides the specifications for the MAX TNT T1/PRI interface and covers cabling requirements.

To reduce the risk of fire, communication cable conductors must be 26 AWG or larger.

Afin de reduire les risques d'incendie, les fils conducteurs du cable de communication doivent etre d'un calibre minimum de 26 AWG (American Wire Gauge), cest-a-dire d'un minimum de 0,404 mm.

T1/PRI CSU requirements

Your T1/PRI requirements depend on whether a T1/PRI port on the MAX TNT is equipped with an internal Channel Service Unit (CSU).

Port with internal CSU

If a T1/PRI port on the MAX TNT has an internal CSU, you can connect the port directly to the metallic interface of the WAN. To avoid harming the WAN, you must contact your carrier for approval before installation. Once you install the MAX TNT, you must notify the carrier before disconnecting the MAX TNT from the WAN. If you disconnect or turn off the MAX TNT without prior notification, the carrier might temporarily discontinue your T1/PRI service.

MAX TNT internal CSUs are compatible with wet- and dry-loop T1/PRI lines and with span-powered or wet-loop powered T1/PRI lines.

Port without internal CSU

A T1/PRI port of the MAX TNT that does not have an internal CSU cannot connect directly to the WAN. You must connect the port to other equipment that provides the interface to the WAN (for example, an external CSU). Your carrier determines the correct value for the line buildout setting of the CSU. You configure this parameter during installation. (For more information, see the Reference Guide.)

T1/PRI cable specifications

The maximum cable distance between the T1/PRI WAN interface equipment and a MAX TNT without CSUs should not exceed 655 feet (200 m). Measure the line length and record it when you install the MAX TNT. You must specify this length when you configure the parameters in the line's profile. (For more information, see the Reference Guide.)

Use only cables specifically constructed for transmission of T1/PRI signals. The cables should meet standard T1 attenuation and transmission requirements. The following specifications are recommended:

The WAN interface cables and plugs described in the following sections are available for the MAX TNT WAN interfaces.

T1/PRI crossover cable: RJ-48C/RJ-48C

Install the RJ-48C/RJ-48C cable when the WAN transmits on pins 5 and 4 and receives on pins 2 and 1. Figure D-1 and Table D-3 show the pinouts.

WAN switched services available to the MAX TNT

The MAX TNT is compatible with both AT&T and Northern Telecom central office switches, and can access all T1/PRI switched digital services offered by AT&T's ACCUNET Switched Digital Services:


Note: The MAX TNT can only access Switched-56 Kbps services on a T1 access line or a Switched-56 line.

For a listing of the compatible switch types, see the Switch Type parameter in the Reference Guide. In addition to connecting to switched circuits, the MAX TNT can connect to nailed-up circuits and to aggregate nailed-up and switched circuits.

Serial WAN cabling specifications

The MAX TNT unit's serial WAN interface supports nailed-up connections to the WAN. Data packets from the MAX TNT bridge/router module can use this interface, but bit streams from devices connected to the MAX TNT serial host ports cannot.

The MAX TNT serial WAN port is compatible with the following two electrical standards:

In the cable wiring tables that follow, the MAX TNT is the Data Terminal Equipment (DTE) that connects to a Data Circuit-Terminating Equipment DCE) device through its serial WAN port. The MAX TNT receives the Send Timing and Receive Timing clocks from the DCE device.

V.35 cable to WAN

You can connect a V.35 cable to the V.35 port of a DCE device. The V.35 cable has the pinouts described in Table D-10.
