Before you begin testing, make sure the HST-3000 setup matches the parameters of the line that you are testing.
The following sections describe how to set the test parame-ters.
NOTE:
To synchronize with the modem at the other end, you only need to set the general modem parameters. To use IP ping or the web browser, you must set the other parameters as well.
Setting general modem parameters
The following procedure describes how to set the general modem parameters.
To set the general modem parameters 1 Press the Configure navigation key.
The parameter soft keys appear.
2 Press the GENERAL soft key.
The General Settings menu appears.
3 Select Phys. Standard, and then change the settings as appropriate for the physical standard in use.
This is the physical standard to which the modem will operate:
– G.991.2 (Annex A) – G.991.2 (Annex B) – G.991.2 (Annex B ANFP) – G.991.2.bis Auto PAM Anx. A/F – G.991.2.bis TCPAM-32 Anx. A/F – G.991.2.bis Auto PAM Anx. B/G – G.991.2.bis TCPAM-32 Anx. B/G – G.991.2 (Annex A) 4-wire – G.991.2 (Annex B) 4-wire – G.991.2 (Annex B ANFP) 4-wire
4 Select Func. Standard, and then change the settings as appropriate for the functional standard in use.
The functional standard is the standard to which the modem will adhere, G.991.2 (used most often), or ETSI TS 101 524-1 (typicaly only used for interoperability with older hardware).
5 Select Auto Sync, and then change the settings as appropriate for auto sync.
This specifies whether the HST-3000 will automatically attempt to re-sync with the DSLAM if the connection drops.
6 Select Power Backoff, and then change the settings as appropriate for power backoff.
When enabled, this allows the transceiver to reduce the transmit power by 6 dB if the estimated line power loss is 6 dB or less.
7 Select Rate Mode, and then specify the baud rate mode.
This selection is only available for 2-wire circuits. The fixed mode requests a particular rate at the connection.
Adaptive mode allows the CPE and the DSLAM to nego-tiate a baud rate.
8 Select Payload Rate, and then enter the data transfer rate.
This is the actual data transfer rate over the circuit. This varies depending on the physical standard. The payload rate should be a number
– between 64 and 2312 for Annex A, Annex B, and Annex B ANFB two wire
– between 192 and 5696 for Auto PAM Annex A/F and Auto TCPAM Annex B/G
– between 768 and 5696 for TCPAM32 Annex A/F and TCPAM 32 Annex B/G
– between 128 and 4608 for Annex A, Annex B, and Annex B ANFB 4-wire
9 If you selected a 4-wire Physical standard in step 3, select Enhanced 4 Wire and specify whether it is enabled.
10 Select ASYMM. PSD, and then select the asymmetric power spectral density (Asymm. PSD) mask setting.
When enabled, this forces the transceiver’s output power level to remain within the G.991.2 requirements. The Auto setting uses the same setting as the other end. If
disabled, power spectral density will be symmetric.
This setting is not available if you are using a .bis Phys-ical Standard.
11 Select Target Margin, and then specify the target SNR margin.
This is the margin value the transceiver will use when selecting the line rate during adaptation. This is only used when the rate mode is adaptive. Choose 0 to 10 dB in 1 dB increments.
12 Select SNEXT Margin, and then specify the self near-end cross-talk setting (SNEXT).
The SNEXT setting is the minimum desired margin using self-NEXT noise model 49 disturbers. This is a dB margin requirement in addition to the noise margin threshold, that makes the connection more robust. However, use of SNEXT may cause a rate reduction as the connection must achieve both this margin and the regular noise margin. Chose -10 to 10 dB in 1 dB increments.
13 Select Event Log Size, and then specify the size of the event log. The size options are as follows: 100, 200, 300, 400, 500.
The general modem parameters are set.
Setting data parameters
To use ping, trace route, FTP/HTTP, or the web browser, the data configuration must be set correctly. The VPI and VCI settings must match the customer-facing settings for the SHDSL ports on the DSLAM.
Be sure to check these settings before you proceed with test-ing. Check the trouble ticket or call your help desk for assis-tance.
The following procedure describes how to specify the data settings.
To set the data parameters 1 Press the DATA soft key.
The Data Settings menu appears.
2 Select Data Mode and then choose a mode.
– IPoE is IP over Ethernet – IPoA is IP over ATM – PPPoA is PPP over ATM – PPPoE is PPP over Ethernet NOTE:
You may achieve synchronization with the DSLAM without configuring these settings, but you must configure these to use ping, trace route, FTP/HTTP, or the web browser.
– Multi-VLAN - Multiple VLANs are used on this network.
In this mode, the HST assumes that the networks that are accessed via each VLAN are unique, and thus provides access to a different range of IP addresses. A typical scenario would be one VLAN for Internet data, another VLAN for Voice, and another VLAN for Video.
– ATM Loopback allows ATM cells to be looped back.
– Bridged Ethernet - HST acts as a layer two bridging device between the WAN and LAN (no routing).
– ATM BERT allows bit error rate testing over the ATM layer.
3 If you are testing in IPoE data mode, select 802.1x Secu-rity and then specify whether 802.1x authentication is supported on your network.
4 If you are testing in IPoE data mode, select STUN Enabled and then specify whether STUN is enabled.
5 If you are testing in Multi-VLAN data mode, select Inter-face Count, and then enter the number of VLANs, between 1 and 3.
Additional setup items appear for each VLAN: Interface Mode and Interface Purpose.
6 If you are testing in Multi-VLAN data mode, select Inter-face x Mode, and then specify the data mode for that sub-interface (IPoE or PPPoE).
7 If you are testing in Multi-VLAN data mode, select Inter-face x Purpose, and then specify the purpose for that sub-interface (Internet, Video, or Voice).
8 Repeat steps 6 and 7 for any remaining interfaces.
9 Select VC, and then enter the virtual path indicator (VPI) and virtual channel indicator (VCI) for the virtual channel (VC) under test.
10 If you selected IPoE, IPoA, PPPoA, PPPoE, MVC Video, or Bridged Ethernet Data Mode, select TX ATM PCR and enter the transmit peak cell rate.
– Unlimited transmits the maximum cell rate allowed on the circuit.
– User Specified allows you to enter a value from 2 to 50000 cells per second.
11 If you selected IPoE, IPoA, PPPoA, or PPPoE Data Mode, select Encapsulation, and then specify the appro-priate setting.
12 If you selected ATM Loopback Data Mode, select Loop-back Mode and specify whether to loop ALL cells or only TTC cells.
The data parameters are set.
Setting WAN parameters
The following procedure describes how to set the wide area network (WAN) parameters. The WAN interface is the DSL connection to tip and ring.
The WAN Settings menu appears if you are using IPoE or Multi VLAN data mode. For Multi VLAN data mode, you may have more than one WAN screen (for example, WAN2, WAN3).
NOTE:
If the rate entered is not attainable, the HST will round down to the next attainable rate.
NOTE:
Depending on previous settings, you may have to navigate to item 10 on the menu, and then press the down arrow to find this selection.

a Select Which MAC, then specify either User Defined or Factory Default.
b If the Which MAC parameter is set to User Defined, enter the appropriate address.
c Select VLAN, then set it to On or Off.
The Virtual LAN (VLAN) setting is only necessary if a VLAN is used to segregate video data flows from other data flows.
If VLAN is on, specify the VLAN ID and VLAN Priority.
4 Press the Home navigation key to return to the Data Summary screen.
The WAN parameters are set.
Setting 802.1x security parameters
The 802.1x Settings menu appears only if you are using the IPoE data mode and “802.1x Security” is set to “Yes” on the Data Settings menu.
IEEE 802.1x offers a framework for authenticating and controlling user traffic to a protected wireless network.
Authentication involves a supplicant (a client device) attempting to connect with an authenticator (the 802.11 access point). The access point (authenticator) blocks all other traffic until it can verify the client's identity. Once authen-ticated, the access point opens the client's port for other types of traffic.
For this authentication, the HST acts as a supplicant. The following procedure describes how to specify the 802.1x settings.
NOTE:
If you are using Multi VLAN data mode and you specify the same settings for different VLANs, a “VLAN CONFLICT”
error will be displayed.
