Specs & Technical Data
Specifications: Integrated CSU/DSU; Transmit bit rate: full T1 at 1.544 Mbps +/- 50 bps, Receive bit rate: 1.544 Mbps +/- 100 bps, Output level (LBO) 0, -7.5, or -15 dB, DSU 0-655 feet, Input level: +1 dB0 to -24 dB0; Recognized BERT Test Patterns: 1:2, 1:5, 1:8, 3:24, QRW, all 0s, all 1s, and user-programmable 24-bit patterns. Requires RJ-48C-to-RJ-48C straight-through cable to connect a T1/FT1 DSU/CSU HWIC to a network. 
Miscellaneous: The HWIC-1DSU-T1 supports wetting current. Wetting current (or sealing current) is the minimum current needing to flow through electrical contacts in order to break through any contact oxidation that may have been deposited on the contacts. Central office sends 60 to 140 mA wetting current to prevent corrosion of electrical contacts in the card's network connection. Wetting current option may be enabled by a J2 jumper on the card. (default setting is "dry" configuration).
