Front Matter vii IMPORTANT SAFETY INSTRUCTIONS Read and follow all warning notices and instructions marked on the product or included in this guide. 1. This product is intended to be used with a three-wire grounding type plug. This is a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the grounding type plug by modifying the plug or using an adapter. 2.
viii Front Matter CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate. The Ringer Equivalence Number (REN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading.
Front Matter ix 5. If the telephone company alters their equipment in a manner that will affect use of this device, they must give you advance warning so as to give you the opportunity for uninterrupted service. You will be advised of your right to file a complaint with the FCC. 6. An affidavit must be completed by the installer. 7. In the event of equipment malfunction, all repairs should be performed by our Company or an authorized agent.

Product Overview Welcome 3 Product Overview Bundled Service deployment is a snap thanks to the ICX-250 from ADC Telecommunications. ADCs’ ICX-250 allows cost-effective and quick deployment of analog voice and data services on a single T1 access trunk. The ICX-250 sports a sleek, low profile chassis and is configured via DIP switches, eliminating the need for PC based craft interface and specialized training.
4 Welcome Product Overview TR-08 The TR-TSY-000008 BellcoreTM standard (commonly referred to as TR-08) describes the generic requirements for interfacing between local digital switches and remote digital terminals via the SLC 96TM digital loop carrier system. TR-08 has three operational modes (ICX-250 supports mode I): • Modes I & III are non-concentrated and provide unique mapping between channel numbers and DS1 time slots.
