7 Section 61245207L2-5, Issue 2 61245207L2-5C 5. CONTROL PORT OPERATION The FT1 DP provides a faceplate-mounted DB-9 connector that supplies an RS-232 interface for connection to a controlling terminal. The pinout of the DB-9 is illustrated in Figure 5.
8 Section 61245207L2-5, Issue 3 61245207L2-5C space bar characters, which are used by the FT1 DP to determine the speed of the terminal. Once the speed has been determined, an Introductory Menu will appear, as illustrated in Figure 6 . From the Introductory Menu, the Main Menu may be selected.
9 Section 61245207L2-5, Issue 2 61245207L2-5C The Current System Status Screen, illustrated in Figure 8 , provides quick access to FT1 DP status information. The Elapsed Time display indicates the period of time since the unit began collecting performance information.
10 Section 61245207L2-5, Issue 3 61245207L2-5C The Performance History Screen displays 15-minute and 24-hour registers for several points in the circuit.
11 Section 61245207L2-5, Issue 2 61245207L2-5C Figure 11 depicts the Self-Test Options Screen. A test of the FT1-DP and the FNID may be initiated from this screen.
12 Section 61245207L2-5, Issue 3 61245207L2-5C The Troubleshooting Display, shown in Figure 13 , graphically depicts a DSL circuit. The unit monitors red, yellow, and blue alarm conditions in the circuit.
13 Section 61245207L2-5, Issue 2 61245207L2-5C 6. DSL DEPLOYMENT GUIDELINES The ADTRAN FT1 DSL system is designed to provide Fractional DS1 based services over loops designed to comply with Carrier Service Area (CSA) guidelines. CSA deployment guidelines are given below.
14 Section 61245207L2-5, Issue 3 61245207L2-5C 7. MAINTENANCE The ADTRAN FT1 DP requires no routine maintenance. In case of equipment malfunction, use the features supplied with the FT1 DP to help locate the source of the problem. ADTRAN does not recommend that repairs be performed in the field.

A-1 Section 61245207L2-5, Issue 3 61245207L2-5C Appendix A FT1 Loopbacks GENERAL This Appendix is an overall reference to the loopback capabilities of the ADTRAN Fractional T1 system. Included in this Appendix is a description of the FT1 loopbacks and the methods for activating the FT1 loopbacks.
A-2 Section 61245207L2-5, Issue 3 61245207L2-5C There is one loopback available to the FT1 Repeaters. The FT1 Repeater Network loopback is a digital loopback toward the CO as shown in Figure A-4 . The loopbacks are initiated by the DDS latching loopback codes for NEI Position 1 (N1000001) for FT1 #1 or NEI Position 2 (N100001) for FT1 Repeater # 2.
A-3 Section 61245207L2-5, Issue 3 61245207L2-5C LOOPBACK ACTIVATION/DEACTIVATION This section describes loopback activation and deactivation methods for the ADTRAN Fractional T1 system. Loopback activation and deactivation is controlled with the push-button located on the front panel, through craft interface, or latching loopback codes.
An important point after buying a device ADTRAN DE-4E (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
If you have not bought ADTRAN DE-4E yet, this is a good time to familiarize yourself with the basic data on the product. First of all view first pages of the manual, you can find above. You should find there the most important technical data ADTRAN DE-4E - thus you can check whether the hardware meets your expectations. When delving into next pages of the user manual, ADTRAN DE-4E you will learn all the available features of the product, as well as information on its operation. The information that you get ADTRAN DE-4E will certainly help you make a decision on the purchase.
If you already are a holder of ADTRAN DE-4E, but have not read the manual yet, you should do it for the reasons described above. You will learn then if you properly used the available features, and whether you have not made any mistakes, which can shorten the lifetime ADTRAN DE-4E.
However, one of the most important roles played by the user manual is to help in solving problems with ADTRAN DE-4E. Almost always you will find there Troubleshooting, which are the most frequently occurring failures and malfunctions of the device ADTRAN DE-4E along with tips on how to solve them. Even if you fail to solve the problem, the manual will show you a further procedure – contact to the customer service center or the nearest service center
