Carrier Access SNMP V.35 DCE Data Port Connections, Abam 600 T1 Cable, 3 24 AWG Twisted-Pair

5.5.2 ABAM 600 T1 Cable

Table 5-4defines the characteristics of shielded 22 AWG ABAM 600 T1 cable. Shielded ABAM 600 has better transmission characteristics and less potential for harmful crosstalk than unshielded 24 AWG twisted-pair telephone cable.

Table 5-4: ABAM 600 T1 Cable Specifications

ABAM 600 Cable	Cable Characteristics
Nominal impedance	100 Ω +/- 5% at 772 kHz.
Insertion loss	Better than 7 dB per 1000 feet at 1.544 MHz.
	Better than 5 dB per 1000 feet at 772 kHz.
Far-end crosstalk	Better than 85 dB per 1000 feet at 1.544 MHz.
	Better than 90 dB per 1000 feet at 772 kHz.
Near-end crosstalk	Better than 80 dB per 1000 feet at 1.544 MHz.
	Better than 85 dB per 1000 feet at 772 kHz.
Signal wires	22 AWG solid tinned copper.
Drain wires	24 AWG solid tinned copper.
Shields	Transmit and receive pairs individually with aluminum/
	polyester tape.

5.5.3 24 AWG Twisted-Pair

In common use throughout the industry, unshielded 24 AWG twisted-pair telephone cable is an acceptable alternative to shielded ABAM 600 for cabling two Access Bank II SNMPs up to a recom- mended distance of 3000 feet. The characteristics of 24 AWG twisted-pair are defined in ANSI/EIA/ TIA 568A (Oct. 1995), Commercial Building Telecommunications Wiring Standards, which is avail- able from:

5.6 V.35 DCE Data Port Connections

The V.35 DCE data port connection is made at the 26-pin micro-D female connector on the Access Bank II SNMP Control Panel (see Figure 5-1)using the 10-foot, 25-foot or 50 foot CAC DTE V.35 Data Cable equipped with a 26-pin micro-D male connector and a 34-pin Winchester male connector.

Note: These cables (005-0008-MM-10’, 005-0009-MM-25’, 005-0010-MM-50’) are optional accessories, and can be purchased from distributors and dealers of CAC products.
