Watson-TDM-Manual-W.doc Watson TDM Operating Manual 2 2.1 Version 2.0-01 Watson TDM Overview Introduction The Watson TDM family is an SHDSL transmission system compliant to ITU-T G.991.2 [11] and to ETSI TS 101 524 [10]. SHDSL uses pulse amplitude modulation (PAM) with 16 or 32 constellations and Trellis coding. Multiple linerates as well as 1-pair, 2-pair, and 4-pair DSL transmission are supported. The Watson TDM modems are available as plug-in cards and as tabletop units.
Watson-TDM-Manual-W.doc Version 2.0-01 2.3 Watson TDM Operating Manual Accessories A range of accessories and system cables are available for the Watson TDM modem family: Plug-in modems can be mounted in a 19" subrack with 12 slots (SZ.379.V3) [6] which has up to 12 free slots for Watson modems. This subrack is normally equipped with an Alarm Control Unit (ACU SZ.369, [2]) which has a serial interface for a configuration terminal (Monitor interface) and two alarm relay outputs.
3 3.1 Watson TDM Features DSL Interface The following configuration options refer to the DSL side and do not affect the user interface operating mode. 3.1.1 Master / Slave To start up a DSL link, one system unit must be configured as DSL master (STUC) and the other one as DSL slave (STU-R). The master controls the link start-up procedure. If both system units are configured as master or as slave, no start-up will occur.
Watson-TDM-Manual-W.doc Watson TDM Version 2.0-01 Operating Manual Some Watson TDM modems also support m-wire operation on 2, 3 and 4 wire pairs. The payload rate, i.e. the data rate available to the application is calculated as follows: [kbit / s ] PayloadRate = m × n × 64 m = number of wire pairs ( 1 Λ 4 ) n = number of timeslots per pair ( 3 Λ 89 ) The linerate per pair is Linerate = n × 64 + OH + Z [kbit / s ] n = number of timeslots ( 3 Λ 89 ) OH = SHDSL Overhead ( 8 kbit / s including 3.

Watson-TDM-Manual-W.doc Watson TDM Version 2.0-01 Operating Manual 3.3 ISDN PRA Interface In PRA mode, the DSL modem offers the functions of an ISDN PRA NT1, an LT or a combination of the functions of NT1 and LT. This allows for the following configurations: • The modem at the customer premises is configured as NT1, the modem at the central office is configured as LT. • The modem at the customer premises is configured as NT1 & LT.
Watson TDM Watson-TDM-Manual-W.doc Operating Manual Version 2.0-01 Depending on the distribution of NT1 and LT functionality, two configurations are possible for option 1: Note: • The master is E1 configured transparent, AIS-generation on and AISdetection off; the slave is PRA NT1 & LT, CRC4 processing off. • The master is PRA LT with CRC4 processing off; the slave is PRA NT1 with CRC4 processing off.
Watson-TDM-Manual-W.doc Watson TDM Version 2.0-01 Operating Manual Digital Link with CRC Processing in the NT1 (Option 2) This is the usual PRA operating mode as described in ETS 300 233 and ITU-T Rec. G.962 Annex B. The PRA interface is intended to be used in this mode.
Watson TDM Watson-TDM-Manual-W.doc Operating Manual Version 2.0-01 Digital Link with CRC Processing in the LT and NT1 (Option 3) In this mode, the NT1 behaves like in option 2. The LT is not transparent, but has CRC4 generation and monitoring in both directions. This option is not possible when using combined NT1 & LT mode, the set-up for option 3 is: • The master is PRA LT with CRC4 processing on; the slave is PRA NT1 with CRC4 processing on.
Watson-TDM-Manual-W.doc Watson TDM Version 2.0-01 Operating Manual Digital Link with CRC Monitoring in the NT1 (Option 4) CRC4 multiframe alignment and checksum words are not regenerated in both directions, i.e. data will be transmitted without changes in both directions. However, blocks with CRC4 errors received from the NT2/TE and the ET will be detected and monitored by the G.826 performance management functions of the modems.
Watson-TDM-Manual-W.doc Watson TDM Operating Manual Version 2.0-01 other errors, e.g. loss of power at NT1 or FC4. To avoid this it is possible to disable Sa6-bit indication. If the CRC4 error notification in Sa6 is enabled, Sa6=0001 indicates an E-bit received from the NT2/TE, Sa6=0010 indicates a CRC4 error detected at the T reference point of the NT1, and Sa6=0011 indicates the simultaneous occurrence of both errors. If disabled, Sa6 is always 0000 in normal operation state.
Watson-TDM-Manual-W.doc Watson TDM Version 2.0-01 Operating Manual 3.4.2 Handshake Operation When no loopback is established, the control circuits perform the following handshake protocol: • 105 (RTS Request to send, X.21: C): Input from DTE. For X.21, C = OFF will cause a DTR alarm. • 106 (CTS Ready for sending, X.21: I): if Handshake option enabled: is set ON when a DSL connection is established and 105 = ON is detected.
Watson-TDM-Manual-W.doc Version 2.0-01 3.4.5 Watson TDM Operating Manual Clock Direction For V.35 and V.36 interface types, the clock direction can be configured by the user. If codirectional, Transmit Data 103 is sampled with Transmit Clock 113. If contradirectional, Transmit Data 103 is sampled with Transmit Clock 114. It is recommended to use codirectional transmit timing whenever possible, in particular for bitrates > 32 x 64 kbit/s. 3.4.6 Clock Polarity In X.
Watson-TDM-Manual-W.doc Watson TDM Version 2.0-01 Operating Manual cuit 114). This clock mode should be used for multiservice operation (simultaneous use of E1 and nx64 kbit/s). • Internal: The transmit clock is generated from the internal reference clock (contra-directional, circuit 114). • Remote: The transmit clock is the recovered remote clock, i.e. the same clock as the receive clock (115) at the V.35 and V.36 interface (contra-directional, circuit 114).

Two DSL links are configured to form a protection group. One link within the group is designated as working link and carries user traffic. The other link is designated the protection link.
Watson-TDM-Manual-W.doc Watson TDM Operating Manual 3.10 Version 2.0-01 Password Protection On tabletop modems the access to the Monitor can be protected by a password to avoid unauthorized reconfiguration of modems installed at the customer site. While in protected mode it is required to enter a password before any Monitor command can be executed from a terminal connected to the local RS-232 port of the modem. Password protection is only active on the local RS-232 port.
4 4.1 Watson TDM Regenerator Operating modes The Watson TDM regenerator has four DSL interfaces. It can be used either as one regenerator for a two-pair system or as a dual regenerator for two independent 1-pair systems. No configuration is needed to select the operating mode. In fact the only configuration command possible on the regenerator is activation and deactivation of the DSL Autorestart, see 8. All other DSL parameters are defined by the DSL master settings. 4.
