5.2Configuration


After entering “Configuration” item on the top of main menu, it will show four items, such as System, Interface, SHDSL and Security.

5.2.1Configuration–System




User may setup IP address via Configuration/System/IP. Setting IP address is required for managing the system via LAN port. This is a must for SNMP, Telnet and TFTP management.







  • Date-Time: The system provides RTC (Real Time Clock) and supports BCD coded century, year, month, date, day, hours, minutes, and seconds with automatic leap year compensation valid up to the year 2100. Set the Date / Time to correctly time-stamping the alarm or PM data report. The date/time will be stored in non-volatile memory, so data will not be lost even when powering off the system (MPU).

  • Default: Reset all the parameters of the device to default values.

  • Reboot: Reboot (restart) the device.


5.2.2Configuration–Interface


There are four DTE interface types, which are SHDSL, E1, T1 and DATA, available for the S1400. In addition, the DATA interface includes V.35, X.21, V36 / RS499, and RS530.

  • SHDSL Performance Monitoring:

The S1400 separately monitor the following performance parameters for the SHDSL loop for each direction of transmission.

(1) Errored Second (ES-crc).

(2) Severely Errored Second (SES-crc).

(3) Loss of Synchronization Second (LOSWS).

(4) Unavailable Second (UAS).

The S1400 separately store the following accumulated performance data for each direction of transmission.

(1) Current 15-minute and at least 32 previous 15-minute periods of parameters as described as above.

(2) Current 24-hour period and at least 7 previous-24 hour periods of parameters as above.



  • T1 (DS1) Performance Monitoring:

The STU-C monitors the T1, as same as DS1, signal from the network side and the customer side separately. The STU-C will maintain separate counts of the following performance parameters for the DS1 line to STU-C and the DS1 line to STU-R such as:

(1) Error Second (ES-DS1).

(2) Severely Error Second (SES-DS1).

(3) Unavailable Second (UAS-DS1).

The S1400 provide a certain number of registers for separately storing the following accumulated performance data for each DS1 line to the STU-C and to the STU-R.

(1) Current 15-minute period and at least 96 previous 15-minute periods of parameters –ES, SES and UAS

(2) Current 24-hour period and at least 7 previous 24-hour periods of parameters as described in ES, SES and UAS.


  • E1 Performance Monitoring:

The S1400 will also monitor the E1 signal from the network side and the customer side separately. The STU-C will maintain separate counts of the following performance parameters for the E1 line to STU-C and the E1 line to STU-R.

(1) Error Second (ES-E1).

(2) Severely Error Second (SES-E1).

(3) Unavailable Second (UAS-E1).

The S1400 provide a certain number of registers for separately storing the following accumulated performance data for each E1 line to the STU-C and to the STU-R.

(1) Current 15-minute period and at least 96 previous 15-minute periods of parameters as above - ES, SES and UAS.

(2) Current 24-hour period and at least 7 previous 24-hour periods of parameters as above - ES, SES and UAS.

5.2.2.1Configuration–Interface–SHDSL






  • Power Back-off: When enabled, the transmit power from the other end of STU will be reduced in 1-dB step from 0 to 6dBs according to the received power. The configurable values are Enable or Disable.

  • Power Scale: The value of this argument adjusts power in small increments (fractions of a dB) to compensate for minor differences in power between testing units.

  • PSD: Possible values are Sym and Asym. Used to let SHDSL transceiver to use a symmetrical or asymmetrical power spectral density mask as specified in G.991.2 standard.

  • 4 Wire: Used to enable or disable 4-wire framing.

  • ANNEX_A_B: Used to select the local STU supporting G.991.2 Annex A or B.

  • Unaligned Mode: Disable or Enable the Unaligned mode (*only for special version to compatible with Alcatel Mainstream 3600 or other devices, this mode can be turned to disable).

A TCA (Threshold Crossing Alert) will be reported if the SNR margin is lower, or if the Attenuation is higher than the set value. The TCA will be time-stamped and logged into local memory and in UNMS database. Users can configure the values of Far End and/or Near End.



  • Threshold Crossing Notification

Threshold values of registers for current 15-minute and current 24-hour performance parameters of ES, SES and UAS that described in, as below, are settable. When the S1400 recognizes a threshold crossing for a given parameter, a threshold crossing notification will be generated and reported to CID and UNMS. All stored performance data will be accessible and cleared from the CID and UNMS.



There are four types of PM parameter thresholds for each combination of near end, far end, 15 minutes, and one day performance monitoring. A TCA will be issued whenever the monitored value has crosses the threshold setting.

The PM count of SHDSL can be cleared whenever desired. Please refer to section 5.3 for more detail operation.

5.2.2.2Configuration–Interface–T1


User has to setup Modem Type first (please refer to section 5.2.3). According to the selected modem type, user can configure interface parameters via Configuration/Interface/Parameters/Near (Far) End. Here we have to set modem type as CO-SHDSL-T1 or CPE-SHDSL-T1.



  • LineType: Possible values are Framed (ESF)+CRC, Framed (ESF), and Framed (SF)(D4).

  • LineCoding: AMI or B8ZS

  • Idle Pattern: Sending pattern on the unused time slots. The possible values are 0x7f and 0xff.

  • Cable Length: Possible values are Short Haul and Long Haul. The T1 circuit provides the function of cable length (from 0 to 200 meters) compensation.

The PM count of T1 can be cleared whenever desired. Please refer to section 5.3 for more detail operation.


5.2.2.3Configuration–Interface–E1


User has to setup Modem Type first (please refer to section 5.2.3). According to the selected modem type, user can configure interface parameters via Configuration/Interface/Parameters/Near (Far) End. Here we have to set modem type as CO-SHDSL-E1 or CPE-SHDSL-E1.



  • LineType: Possible values are Framed_CRC, Framed (no CRC) and Unframed.

  • Impedance: Normal 120 ohms resistive symmetrical (Balance) pair.

  • Idle Pattern: Bit sending pattern in the unused time slots. The possible values are 0x7f and 0xff.

The PM count of E1 can be cleared whenever desired. Please refer to section 5.3 for more detail operation.


5.2.2.4Configuration–Interface–DATA


User has to setup Modem Type first (please refer to section 5.2.3). According to the selected modem type, user can configure interface parameters via Configuration/Interface/Parameters/Near (Far) End. Here we have to set modem type as CO-SHDSL-DATA or CPE-SHDSL-DATA.



  • DTE Type: V35, V36 / RS449, RS530, or X21.

  • Exc-pin detect: enable or disable the external clock pin detection of V.35 interface.

  • Tx/Rx data inversion: normal or inverse. The V.35 interface of STU-R provides data inversion capability used to protect against the occurrence of low pulse density.

  • CTS: Always ON (default) or Follow RTS of V.35 interface.
