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 wide ly used by the tel cos . Communica tion 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 topograph ies for voice. The techn ologic al advan ces in computer d evelopment also created a demand for T1 data communication, which now is a large part of the T1 traffic.

T1 SERVICE OFFERINGS

T1 is a digital service delivered to the user over two pairs of wires from the service provider. The signal operates at 1.544 Mbps and is usually extended by repeaters installed approximately every mile after the first 6000 feet. The T1 s ig nal is divided into 24 time slot s whi ch operate at 64 kbps (DS0s). Ea ch time slot is occupied by digitized voice or by data.

The T1 signal original ly used a t ype of fr aming kno wn as D4 superf rame (SF), wh ich id entifies ho w the T1 is multiplexed. An enhancement of that framing format, called extended superframe (ESF), is available. ESF provides a non-disruptive means of full-time monitoring on the digital facility. It was originally used by service providers to monitor the performance of their service offering. Since the introduction of ESF, equipment installed in private networks can also provide this performance information to the user.

T1 ESF CSU ACE OVERVIEW

Most carriers (regional or local telcos), when supplying a T1 line to customer premises equipment (CPE), require an interface to monitor the T1 line. The T1 ESF CSU ACE (extended superframe channel service unit advanced communicat ion equipment) pro vides the requi red interfac e between the CPE (such as DSUs, channel banks, T1 multiplexers, and PBXs) and telco or private T1 facilities. Figure 1-1 depicts a typical application.

Page 23

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 fr ont panel LCD displays the st atus of operatio n and performance rep orts 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. It provides complete control over the configuration of the T1 ESF CSU ACE through a graphic interface. The T-Watch program displays the same status and performance data as the front panel LCD. This data is displayed in the form of tables and graphs.

The T-Watch program has the following capabilities:

• Interface with mode m permits d ialing int o a remot e T1 ESF CSU ACE l ocation to configur e the uni t or read the unit’s status or performance.

• Performance data read from the units can be exported in a file which is compatible with common spreadsheet programs.

SNMP

The ADTRAN T1 ESF CSU ACE supports the Simple Network Management Protocol (SNMP) through the ADTRAN Advisor SNMP Proxy Agent (1950007L1) to a network management system such as OpenView® or SunNet Manager™. The proxy agent runs on a PC and can interface to the T1 ESF CSU ACE directly or through a modem, in the same manner as the T-Watch PC programs.

ASCII Terminal

The ADTRAN T1 ESF CSU ACE recognizes an escape s equence th at puts t he unit into the ASCII terminal mode. After receiving the sequence, the T1 ESF CSU ACE sends front panel information to the terminal. This interface acts exactly like the front panel, but the advantage is that it can be accessed remotely (through a modem). The escape sequence is:

<CONTROL-A> <CONTROL-P> <CONTROL-T> or <CONTROL-P> <CONTROL-T> <CONTROL-T>

The terminal or terminal emulation software must be VT100 compatible.

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. Although actual user data cannot be passed during these tests, the self test can be run with the network and DTE interfaces in place and will not disturb any external interface.

The self test automatically executes upon power-up. It can also be initiated from a front panel menu or from the control port.

In addition to the specified self tests, background tests are run on various parts of the internal electronics. These run during normal op era tion to co nfirm conti nued c orrect func tioni ng. The backgr ound t ests incl ude the standard background network performanc e mon it ori ng as required by ANSI T1.403 a nd AT&T 54016, for which the results are stored.

Page 25

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.

Network Loopbacks

There are two types of network loopbacks: line loopbacks and payload loopbacks. These are illustrated in Figure 1-5.

• Line Loopback - Loops all of the received data back toward the network. The transmitted data is the identical line code that was received, including any bipolar violations or framing errors.

• Payload Loopback - Similar to line loopback, except that the framing is extracted fr om the received data and then re generated fo r the transmitted data.

Figure 1-5. Network Loopback Tests

DTE Interface Loopbacks

Loops all data from the terminal interface (TI) back towards the T1. This loopback may be initiated using front panel, EIA-232 control port, or T- Watch commands. The DTE (or external test equipment) must provide any test pattern in order to check the DTE interface. See Figure 1-6.

Figure 1-6. DTE Interface Loopback

Page 26

Chapter 1. Introduction T1 ESF CSU ACE User Manual

Pattern Generation

The T1 ESF CSU ACE offers three test patterns: All Ones, All Zeros, an d 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).

1 in 8 (1:8)

Each channel of the T1 has only one bit set. This pattern is used in conjunction with external test equipment to determine whether the T1 line is performing acceptably under a stress condition.

APPLICATIONS

Three applications are shown in this section. Figure 1-7 on page 27 shows a general data application; Figure 1-8 on page 28 shows a general voice applicati on; and Fi gure 1-9 on page 28 shows a channel bank application.

POWER-UP TESTING AND INITIALIZATION

When shipped from the fac tory, the T1 ESF CSU ACE is set to factory default conditions . When power i s applied, the unit automa tically executes self test, followed by an initializatio n 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. When the self test is completed with no failure s detected, the LCD momentarily displays ALL TESTS PASSED. If a failure is detected, it is displayed in the LCD window. The automatic self test procedure consists of the following steps:

1. Board level tests - RAM te sts; EPROM checksum

2. Unit level tests - Front panel LED verification

Data Values

1)NI PERF RPTS, Submenu of 1)STATUS

The Network Interface Performance Reports menu item displays the user copy of the performance data. The T1 ESF CSU ACE maint ains th is performanc e data on the netwo rk in compl iance with ANSI T1.403 and AT&T document TR54016. The data displayed is data accumulated over the last 15 minutes and over the last 24 hours.

Figure 3-10. First Menu of NI PERF RPTS Menu

These fields cannot be edited, only cleared, as previously discussed. Only the user copy of the performance data is cleared. The network management performance data history remains unaffected.

Separate carrier totals are kept which can only be retrieved and reset from the network.

Figure 3-11. Performance Counter Screen

The counters used in the performance screens are defined below.

SES Number of severely errored seconds ES

Number of errored seconds

%AV Percent of available seconds %EF Percent of error free seconds CVs Number of code violations

Continue with standard operation procedures to exit the display.

Since only the user’s copy of performance data is cleared by the T1 ESF CSU ACE, the data displayed here might be different from the data being sent to the network as maintenance message data.

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 Deactivates the loopback DTE ON Activates the DTE loopback LINE ON Activates the line loopback PAYLOAD ON Activates the payload loopback

Figure 3-20. Local Loopback Test Screen

2)REM LB, Submenu of 4)TEST

Activates the same loopbacks as th e LOCAL LOOPBCK but at the far end. This uses eit her the inband loop-up code as specified by AT&T 62411 for line loopback (ATT In-Band LLB), or the FDL as specified in ANSI T1.403 for line loopback codes. An FDL (formerly TABS) maintenance message corresponding to AT&T TR54016 can be used for payload loopback as well:

NO LOOPBACK Deactivates the loopback

AT&T INBAND LLB Activates the line loopback using inband code. ANSI FDL LLB Initiates the transmission of an FDL line loop-up code toward the far end. AT&T FDL

PLB Initiates the transmission of the PLB maintenance messages on the FDL.

When a loopback method i s s el ect ed, the T1 ESF CSU ACE displ ays LOOPI NG in t he top right corner of the LCD and the yellow LOOPBACK LED is turned on. When the T1 ESF CSU ACE determines that the far-end T1 ESF CSU ACE has looped up, the T1 ESF CSU ACE displays LOOPED. If the T1 ESF CSU ACE does not recognize the remote T1 ESF CSU ACE looped up after about 10 seconds, the T1 ESF CSU ACE sends the appropriate loop-down code and displays FAILED, and the LOOPBACK LED is turned off.

Excessive errors on the T1 line can cause this failure. The FDL loopbacks fail if the FDL is not intact from one end point to the other. FDL loopbacks are valid only in the ESF framing mode.

Page 50

Chapter 3. Operation T1 ESF CSU ACE User Manual

3)TEST PATTERN, Submenu of 4)TEST

Sets the pattern for the test and initiates the transmission of the pattern. The test is terminated by selecting NO PATTERN. There are four patterns available:

NO PATTERN Terminates pattern generation. ALL ZEROS Generates an all zeros pattern in every channel . 1:8 ALL DS0s Generates a 1 in 8 pattern in all DS0s. ALL ONES Generates an all ones pattern in every channel.

bridge

A device that supports L AN-to-LAN comm unications. B ridges m ay be equipp ed to provid e frame relay s upport to the LAN devices they serve. A frame relay capable bridge encapsulates LAN frames in frame relay frames and feeds them to a frame relay switch for transmission across the network. A frame relay capable bridge also receives frame relay frames from the network, strips the frame relay frame off each LAN frame, and passes the LAN frame on to the end device. Bridges are generally used to connect LAN segments to other LAN segments or to a WAN. They route traffic on the Level 2 LAN protocol (e.g. the Media Access Control address), which occupies the lower sub-layer of the LAN OSI data link layer. See also router.

CCITT

encapsulation

A process by which an interface device places an end device’s protocol-specific frames inside a frame rely frame. The network accepts only frames formatted specifically for frame relay; therefore interface devices acting as interfaces to a frame relay network must perform encapsulation. See also interface device or frame relay capable interface device.

end device

The ultimate source or destination of data flowing through a frame relay network sometimes referred to as DTE. As a source device, it sends data to an interface device for encapsulation in a frame relay frame.
