3.0 INSTALLATION
The Model 1007 is easy to install. This section tells you how to properly connect the Model 1007 to the twisted pair interface and Mac phone port, and how to operate the Model 1007.
3.1 CONNECTION TO THE TWISTED PAIR INTERFACE
The Model 1007 supports
1.These units work in pairs. You must have one Model 1007 (or a compatible model) at each end of the two twisted pair cable.
2.To function properly, the Model 1007's modular jacks must be con- nected to two twisted pairs of metallic wire. The pairs must be unconditioned, dry metallic wire, between 19 and 26 AWG (the higher number gauges may limit distance). Standard
For your convenience, the Model 1007 is available with two differ- ent twisted pair interfaces: an

When connecting two Model 1007s, it is necessary to use a
“crossover” cable. The diagram below shows how a crossover cable should be constructed for an environment where both Model 1007s use a

3.2 CONNECTION TO THE MAC PHONE PORT
The Model 1007 should be connected to your Mac through the 1 foot extension cable. Simply plug one end of the cable into the Model 1007 and the other end directly into the phone (serial) port of your Mac. The
