T-ONE 100 Ohm I/O Card - Model No. EXSTIO1000

You are here: Excel CSP Hardware Product Descriptions > 3 Line Cards > T-ONE 100 Ohm I/O Card - Model No. EXSTIO1000

The T-ONE 100 Ohm I/O card connects the CSP to T1 lines and other telecommunications equipment.

Use only 100 Ohm impedance shielded twisted-pair cable in compliance with ITU-T G703. Do not use flat wire. Wire the interface connection in accordance with ANSI 50-position RJ48M pinout specifications. The table below shows the T-ONE 120 Ohm I/O pinout.

The T-ONE 100 Ohm I/O card resides in the rear card slots of an
CSP 2090, CSP 2110 or CSP 2040 chassis.

The part number, serial number, model number, and revision are located on the back of the board.

The T-ONE 100 Ohm I/O card is designed to the following electrical, physical and environmental specifications.

The T-ONE 120 Ohm I/O card complies with all relevant regulations from the following standards organizations and governing bodies.

An I/O card that supports redundancy and has external connections. It sits behind whichever line card is originally designated as "active." Compare to "Standard I/O card" and "Standby I/O card."

An I/O card that supports redundancy but has no external connections. A Standby I/O card sits behind whichever line card is originally designated as "standby." Compare to "Redundant I/O card" and "Standard I/O card."

Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.
