When you set the reference for twisted pair tests, you usually connect the DSX main and remote testers together with a permanent link adapter and a channel adapter.

The reference module is included with the DSX-CHA12S adapter kit. You may also purchase the module, model name DSX-REFMOD, as an accessory.
