T1/FT1 OVERVIEW
The T1 digital communications link has been used by telephone companies (telcos) for transmitting voice since the early sixties. The D4 channel bank is a T1 digital carrier system that was introduced in the mid seventies and is still widely used by telcos. Communi­cation demands of businesses continued to grow to the point that the telcos began offering T1 service directly to the public. D4 channel banks began to be used for T1 in corporate network topographies for voice. The technological advances in computer development also created a demand for T1 data communication which now is a large part of the T1 traffic.
Chapter 1. Introduction
Chapter 1
Introduction
T1 Service Offerings
T1 is a digital service that is 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 that are installed about every mile after the first 6000 feet. The T1 signal is divided into 24 time slots which operate at 64 kbps (DS0s). Each time slot is occupied by digitized voice or by data.
The T1 signal originally used a type of framing known as D4 Superframe which identifies how the T1 is multiplexed. An enhancement of that framing format, called Extended Superframe Format (ESF), is avail­able. It provides a non-disruptive means of full time monitoring on the digital facility. The ESF was originally used by the service provider to monitor the

Chapter 1. Introduction
Fractional T1
performance of their service offering. Since the introduction of ESF, equipment that is installed in private networks can also provide the same perfor­mance information to the user.
Fractional T1 (FT1) lets the buyer purchase less than a full T1 circuit between two points. Most carriers offer fractional T1 in increments of 56 or 64 kbps. Connec­tion is made to the same network elements. The network allows multiple users to share the same interoffice T1 bandwidth.
Fractional T1 remains almost exclusively an Inter­Exchange Carrier (IXC) service. Local Exchange Carriers (LECs) typically do not offer FT1, so the proximity of the user to the point of presence (POP) of the IXC is key in the savings that fractional T1 offers.
Fractional T1 local access is available in two forms, 56 kbps or a full T1 line. In 56 kbps the required number of DDS lines is extended from the IXC POP and the bandwidth is combined at the office on an outbound T1 circuit. The user pays for the individual 56 kbps lines and the amount of the interoffice T1 utilized. In T1 access, the user pays for a full T1 to the IXC POP and then only for the bandwidth utilized.

61200.076L2-1 TSU 600 User Manual 3
Chapter 1. Introduction
The TSU 600 serves as the link between user data sources such as local area network (LAN) bridges and routers, computers, CAD systems, teleconferencing equipment, and PBXs. Through the use of multiple data ports, the TSU 600 can simultaneously connect one or more of these devices to a T1 circuit. The amount of bandwidth allocated to each port is custom programmable. The bandwidth allocation can be changed manually or set to automatically change at predetermined times to use the available bandwidth most advantageously. Changes in the configuration are accomplished without disrupting data flow in channels that are not being reconfigured. The unique architecture and the availability of the option modules provides a path for growth to accommodate future requirements.

THREE 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 also displays the status of operation and performance reports for the unit. A complete discussion of the operation of the front panel and all the menu options is found in the chapter
Operation.
ADTRAN PC Program
T-Watch is the ADTRAN PC control program for Microsoft Windows®. It provides complete control over the configuration of the TSU 600 using a graphic interface. The T-Watch program displays the same status and performance data as the front panel LCD. These data are displayed in the form of tables and graphs.
Chapter 1. Introduction
The T-Watch program has the following capabilities:
• Interfaces with a modem which permits dialing into a remote TSU 600 location to configure the unit or read the unit's status or performance.
• Receives traps from the TSU 100 network alarm.
SNMP
The ADTRAN TSU 600 is designed to support the Simple Network Management Protocol (SNMP) through an ADTRAN ADVISOR. The proxy agent runs on a PC and can interface to the TSU 600 directly or through a modem, in the same manner as the T­Watch PC program.

OPTION SLOT ARRANGEMENT
As viewed from the rear of the TSU 600, the slots are numbered as shown in Figure 1-4. All slots are functionally identical except slots one and six. These slots offer additional functions.
Slot 1
Slot 1 is used as the source of DTE timing when the DTE timing mode is selected. If DTE timing is de­sired, the DTE interface port sourcing the timing must be connected to Slot 1. This slot will accept all other interface types except Secondary Network interface option modules, including DSX-1 (PBX), the Full Drop and Insert (D&I) network interface, or the Dial Backup (DBU).
Slot 2
Slot 2 is used for the Dial Backup module if a DBU is installed. This slot accepts all other interface types except Secondary Network interface option modules, including DSX-1 (PBX) and the Full Drop and Insert (D&I) network interface.
Slots 3-5
Slots 3-5 will accept any interface type except second­ary interface, the interface for DTE timing, or the DBU. If other interfaces have any restriction on their loca­tion, this will be specified in the individual option card manual (provided with the option cards).

OPTION PORTS
The option ports vary depending on the option modules installed.
Secondary Interfaces (SI)
The secondary interface is an additional interface to a DS1, a DSX1 facility, or some other network service, and it offers a source of timing. The type of interface depends on the option module installed. The interface includes the following:
• DSX1. Passthru for operation with a PBX (Terminal Interface - TI).
• Full Drop and Insert. Permits the dropping of data and insertion of new data into the same DS0 time slot. This SI module includes a long haul DS1 interface. It can also be used as a second DS1 interface to provide an up to 3 Mbit aggregate throughput.
Other Data Interfaces
Additional data interfaces can be installed in the option slot, and include the following:
• Nx56/64 serial interface. This module is the same as the base Nx interface but offers single or dual V.35 ports.
• Voice interface. 2/4 channel FXS/FX0/E&M.
• OCU DP. Interfaces to DDS or 4-wire Switched 56.
• Dial backup.

TSU 600 CLOCK SOURCES
The TSU 600 is operable from various clock sources permitting it to perform properly in many different applications. The network interface clocking options are set by using the clocking options set by using the Network (NI) Configuration menu options. The following clock source options are available:
• Network
• DTE timing
• Internal timing
• Secondary timed
• Normal (CSU)
The clock option selected always designates the clock source for transmission. Clocking necessary for receiving data is always recovered from incoming data.
Network Timed
The network is the source of timing. The received data clocking is looped back to the network where it is used to determine the transmission timing. This option is also referred to as loop timed as the transmission clock is derived from the received clock. See Figure 1-5.

Chapter 1. Introduction
DTE Timed
The DTE is the source of timing. The TSU 600 uses the incoming DTE clock to determine the transmission timing. This is typically used in applications where it is necessary to have the DTE as the primary clock source, (such as limited distance line drivers). See Figure 1-6.
The DTE source timing is restricted from use when a secondary interface is used at the same time.

Internal Timing
Chapter 1. Introduction
The TSU 600 is the source of timing. The TSU 600 is configured to use its own internal oscillator as the source of timing. Applications include private line driver circuits where one end is set to network and the other to internal. See Figure 1-7.
The internal source timing is restricted from use when a secondary interface is also used.

Normal (CSU) Timing
The typical timing option arrangement is shown in Figure 1-8. The PBX is looped timed sending data to the TSU 100 which is actually synchronous to the received data. The Network Interface (NI) is the actual source of all timings. This timing option is the same as that typically used for CSUs. This is the preferred mode for use with a PBX application.

TSU 600 TESTING
The TSU 600 offers three forms of testing:
• Self test
• Loopback tests (local and remote)
• Pattern generation and check
Self Tests
The self test checks the integrity of the internal operation of the electronic components by performing memory tests and by 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 memory portion of the self test automatically executes upon power up. A full self test can be com­manded from a front panel menu or from T-Watch.
In addition to the specified self tests, background tests are also run on various parts of the internal electron­ics. These run during normal operation to confirm continued correct functioning. The background tests include: (1) monitoring the phase locked loop for lock, (2) sending test data through a parallel path which is looped back and verified, and (3) the standard back­ground network performance monitoring, as required by ANSI T1.403 and AT&T 54016 specifications for which the results are stored.
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 in-band codes (AT&T D4 network loop up and loop down codes; V.54 loop up/ loop down codes for the Nx56/64 serial interface). Additionally, the loopbacks can be remotely controlled by means of out-of-band commands by the T1 ESF FDL or from T-Watch by a modem connection.

Chapter 1. Introduction
Classes of Loopbacks
NI CSU
DS1
There are two classes of loopbacks: network interface and DTE interface.
Network Interface Loopbacks
Network interface loopbacks (see Figure 1-9) affect the entire T1 data stream. There are two types of network loopbacks, line loopback and payload loopback.
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 is similar to line loopback, except that the framing is extracted from the received data and then regenerated for the transmitted data.

Network Loopback Tests
DTE Interface Loopbacks
DTE interface loopbacks affect only that portion of the data stream programmed to that particular interface port. The Nx56/64 serial interface offers two loop­backs, a DTE loopback and a port loopback. See Figures 1-10 and 1-11.
DTE loopback loops all data from the DTE back towards the DTE. This loopback occurs just past the interface circuit allowing a verification of the opera­tion of the DTE to TSU 600. This loopback may be initiated by using front panel or T-Watch commands. The DTE (or external test equipment) must provide any test pattern in order to check the DTE interface. See Figure 1-10.
