| 1 1 Introduction Welcome to the Nx12 The Telos Nx12 combines a 12-line selector and 4 hybrids with advanced signal processing to deliver all you need for your on-air phones. The four hybrids make it ideal for programming where multiple callers are aired simultaneously. It also has the flexibility to serve two studios with two hybrids for each. At the heart of any broadcast telephone system are the hybrids and associated signal processing. Based on the latest Telos technology, the Nx12

In the latter case, there is no possibility for accidental interaction. ♦ Support for up to eight Desktop Directors. ♦ Compatibility with Telos Assistant Producer and third-party ca

Analog lines are exposed to a variety of noise and impulse trouble-causers as they snake across town on poles and through your building. Hum is the main problem, given most lines’ proximity to pole transformers and AC power wires, but there is also impulse noise from motors, switches, and other sources. Digital lines c

4 | section 1 Two-Studio Modes The Nx12 can be used with two studios independently. Lines may be independent or shared. Each studio has two hybrids. There are two Progam-on-Hold inputs, one for each studio. Two sets of Telos’ Assistant Producer application can be used independently. Note the following: ♦ With analog audio in/out, there are only two total inputs and outputs. So the Nx12 must be used in a mode that combines the two hybrids assigned to each studio into one input/ output. ♦ The

| 5 2 Installation 2.1 Getting Started The Nx12 mounts in a 2RU high space in a standard 19” rack. You do not need to pay special attention to cooling or ventilation, as the unit will operate in any environment where the stirred air temperature around the unit is between 0 to 40 degrees Celsius (32 to 104 degrees Fahren- heit) with a relative humidly of 0 to 98% (non-condensing). Next installation steps are: ♦ Connect the Telco circuits. Learn about telephone service options. ♦ Connect a

6 | section 2 2.3 Connecting the Nx12 to Analog Lines The Nx12 uses plug-in interface modules to attach to POTS (regular, analog loop start, telephone lines). The Country setting in the Telco menu configures the characteristics of the interfaces for your country. If you do not see your country listed you should use CTR21 or USA. These modules have 6 modular jacks. The type of jack will be a 6 position 4 pin RJ-11 style. The connection is to the center two pins of this jack. Note: Unlike our

Ins Talla TIon | 7 In the USA & Canada a direct connection to the “bare copper” 2-wire U interface is required. Therefore, the USA & Canada interface module includes an integral NT1 and has RJ-11 style jacks. In the rest of the world, the telephone company provides the NT1, and the 4-wire ISDN S-interface will be used with an 8 pin RJ-45 style jack. Normally we ship Nx12s to North America with the U-interface module and to other areas with the S-interface module. In either case each ISDN in

Both include ready-to-go forms that can be sent directly to your telephone company. 2.5 Connecting the Nx12 to ISDN The Nx12 uses plug-in modules to attach to ISDN. These ISDN modules have three modular jacks. The type of jack will be either a 6 position RJ-11 style or an 8 position RJ-45 style depending upon whether it is t

Ins Talla TIon | 9 Hot Tip Normally your telephone company should supply an RJ-11 style jack for the U interface. This is the same 4 or 6-pin plug used for analog lines. However, sometimes you may find an 8-pin RJ-45 style jack–and sometimes you may even be charged extra for it! If you have this situation, an RJ-11 plug can be inserted into the center of an RJ-45 jack to make things work. If you discover that the Telco charged you extra, be sure to request a refund!

10 | section 2 2.6 Integration with a PBX The Nx12 will usually be used independently of any other phone system in your facility. But it is possible to have one or more of the lines come off another phone system. Depending upon the PBX and your preferences, this can be either ISDN BRI or POTS. You might be able to save money by using a T1/E1 or ISDN PRI as your Telco link and having the PBX generate local ISDN BRI or POTS lines for the Nx12. Consider having at least one line directly from
