Chapter 1 Introduction T1/FT1 OVERVIEW T1 digital communication links have been used by telcos for the transmission of voice since the early sixties. The D4 channel bank is an example of a T1 digital carrier system that was introduced in the midseventies and is still widely used by the telcos. Communication demands of business continued to grow to the point that the telcos began offering T1 service directly to the public. D4 channel banks were used for T1 in corporate network topographies for voice.

T1 ESF CSU ACE Application The T1 ESF CSU ACE provides surge protection, signal regeneration, alarms, and loopbacks necessary for circuit operation and fault isolation. The unit provides the simultaneous use of performance report messages of ANSI T1.403 and maintenance messages of AT&T TR54016.
T1 ESF CSU ACE User Manual Chapter 1. Introduction Figure 1-3. T1 ESF CSU Rear View Figure 1-4. Jack Signal Directions Features The following features give the T1 ESF CSU ACE many advantages over other products of its kind: • • • • • • • Smallest T1 ESF CSU ACE in the industry. Front panel interface eliminates the need for a terminal to configure the T1 ESF CSU ACE. Automatic ESF to D4 frame conversion. Wall mount NEC Class 2, 12 VDC power supply eliminates the need for an external power supply.
Chapter 1. Introduction T1 ESF CSU ACE User Manual Interface Features NI (Labeled NET) The network interface (NI) port complies with the applicable ANSI and AT&T standards.
T1 ESF CSU ACE User Manual Chapter 1. Introduction FOUR METHODS OF CONTROL Front Panel The front panel provides complete and easy control of all items that can be configured through menu-guided options. The front panel LCD displays the status of operation and performance reports for the unit. Chapter 3 contains information on front panel operation and all the menu options. ADTRAN PC Program T-Watch is the ADTRAN PC control program.
Chapter 1. Introduction T1 ESF CSU ACE User Manual T1 ESF CSU ACE TESTING The T1 ESF CSU ACE offers three forms of testing: • • • Self test Loopback tests Pattern generation Self Test The self test checks the integrity of the electronic components’ internal operation by performing memory tests and sending and verifying data test patterns through all internal interfaces.
T1 ESF CSU ACE User Manual Chapter 1. Introduction Loopback Tests A number of different loopbacks can be invoked locally from the front panel, by T-Watch commands, or remotely by using special inband codes (AT&T network loop-up and loop-down codes). Additionally, the loopbacks can be remotely controlled by out-of-band commands using the T1 ESF FDL, or from T-Watch using a modem connection. A discussion of network loopbacks and DTE interface loopbacks follows.
Chapter 1. Introduction T1 ESF CSU ACE User Manual Pattern Generation The T1 ESF CSU ACE offers three test patterns: All Ones, All Zeros, and 1:8. These patterns can be initiated from the front panel, through the EIA-232 control port, or remotely via a management software like T-Watch. All Ones The All Ones pattern sends ones in all the payload bits. All Zeroes The All Zeros pattern sends zeros in all the payload bits and is useful for testing line code configuration (AMI/B8ZS mismatches).

Chapter 2 Installation UNPACK AND INSPECT Carefully inspect the T1 ESF CSU ACE for any shipping damages. If damage is suspected, file a claim immediately with the carrier and then contact ADTRAN Technical Support. If possible, keep the original shipping container to ship the T1 ESF CSU ACE back for repair or to verify damage during shipment.
Chapter 2. Installation T1 ESF CSU ACE User Manual Method 2 • Connect to a reliably-grounded 12-48 Vdc source which is electrically isolated from the AC source having LPS or NEC Class 2 outputs OR • Use a Listed Class 2 Direct Plug-In Supply with an output rated 12-48 Vdc, minimum 350 mA, maximum 240 VA. Note: The branch circuit overcurrent protection shall be a fuse or circuit breaker rated at a minimum of 48 V to a maximum of 10 A.
T1 ESF CSU ACE User Manual Chapter 2. Installation POWER-UP TESTING AND INITIALIZATION When shipped from the factory, the T1 ESF CSU ACE is set to factory default conditions. When power is applied, the unit automatically executes self test, followed by an initialization sequence that sets up the unit. Self Test Upon a power-up or self test, the LCD displays ADTRAN T1 ESF CSU ACE INITIALIZING and the LEDs illuminate momentarily.

Chapter 3 Operation The T1 ESF CSU ACE can be configured and controlled via the local front panel, the EIA-232 control port, or T-Watch. This chapter describes configuration from the front panel. FRONT PANEL OPERATION The T1 ESF CSU ACE front panel operating functions are shown in Figure 3-1 and defined in this section. Figure 3-1.
Chapter 3. Operation T1 ESF CSU ACE User Manual GENERAL FRONT PANEL MENU OPERATION The T1 ESF CSU ACE uses a multilevel menu structure containing both menu items and data fields. All menu operations and data are displayed in the LCD window. The menu items are numbered and can be viewed by using the scroll keys (the arrow keys on the front panel). Description of Menu Tools Data Field A menu item followed by a colon (:) identifies a field available for editing.
T1 ESF CSU ACE User Manual Chapter 3. Operation Selecting a Submenu Item To select the desired submenu item (similar to selecting a Main menu item), follow these steps: 1. Use the up and down scroll keys to place the cursor on the desired menu item, in this example 1)NETWORK (NI). See Figure 3-3. 2. The unit responds by displaying the first two available data field items. The cursor is on the number of the first item.
Chapter 3. Operation T1 ESF CSU ACE User Manual View Display Only Data Fields Select the following menu choice to view an example of a display-only data field: 1. Select 1)STATUS from the Main menu. 2. Select submenu 2)NI ERR/ALM. 3. LOSS OF SIGNAL INACTIVE/ACTIVE displays, giving the current state of the alarm. Exiting or Returning to Previous Menus Press the CANCEL key to exit a menu field or return to a previous menu level.

T1 ESF CSU ACE User Manual Chapter 3. Operation 2)NI ERR/ALM, Submenu of 1)STATUS The NI ERR/ALM menu is used for viewing currently active/inactive errors and alarms on the network interface. Figure 3-12. First Current NI Errors/Alarms Screen The up and down scroll keys are used to access the complete display of the errors/alarms that are currently active.
Chapter 3. Operation T1 ESF CSU ACE User Manual 5)TI HISTORY, Submenu of 1)STATUS The T1 HISTORY screens are the same as the NI HISTORY screens except that they correspond to the terminal interface. 2)CONFIG Use the Configuration menu to set the T1 ESF CSU ACE operational configuration, including all of the network interface parameters and the terminal interface parameters. See Figure 3-14.
T1 ESF CSU ACE User Manual Chapter 3. Operation Continue with standard operating procedures to edit the Network Interface parameters. The fields and parameters available are as follows: 1)FORMAT Sets the frame format for the NI. The factory default is ESF. D4 ESF D4 is equivalent to superframe format (SF). 2)CODE Sets the line code for the NI. The factory default is B8ZS. AMI B8ZS 3)YEL ALRM Enables and disables the transmission of yellow alarms. The factory default is ENABLED.
Chapter 3. Operation T1 ESF CSU ACE User Manual 6)BIT STUFFING When enabled, bit stuffing causes the T1 ESF CSU ACE to monitor for ones (1s) density violations and inserts a one (1) when needed to maintain ones at 12.5 percent. This option should be disabled if B8ZS is enabled. The factory default is DISABLED. ENABLED DISABLED 7)SET LBO Selects the line build out for the network interface. The factory default is 0 dB. 0 dB -7.5 dB -15 dB -22.

Chapter 3. Operation T1 ESF CSU ACE User Manual 3)TEL NUM - This is the telephone number dialed for alarm traps transmission. The string can be up to 20 characters in length and is terminated with a semicolon (;). A colon (:) is used to represent a pause in the dial string. Example: Number 9:5551212; would dial 9, pause momentarily, and then send 5551212. This pause could be effected to access an outside line from a PBX, etc.

Use this option to select the remote unit type, ID, and slot number. The ID and slot number are only applicable if the selected remote unit is rackmount, so these may be left blank if the remote unit is standalone.
T1 ESF CSU ACE User Manual Chapter 3. Operation Tests are used to control the activation of loopbacks, the initiation of data test patterns, and self test execution. 1)LOCAL LOOPBK, Submenu of 4)TEST Four choices are available for setting the local loopback: NO LOOPBACK DTE ON LINE ON PAYLOAD ON Deactivates the loopback Activates the DTE loopback Activates the line loopback Activates the payload loopback Figure 3-20.
