STATE

The State setting de termines whether the port is active or inactive . An inactive port does not occupy time slots on a WAN link. Set State to standby (stdby) for ports you are not using or have not yet configured. Set it to active (actv) for ports that are ready for use. The control leads assume the status shown in Table 1-6 for the different states.

WAN/SRV

The WAN/SRV setting identifies the card to which the output of this port is direc ted. If wan is chosen, the data fr om this car d port will be dir ected t o a WAN port (the options are w1-1 to w4-2).

If user is chosen, the data will be routed to another HSU Card. First, highlight the selected user slot (U1 to U8). Then, if there is a compatible HSU Card in that slot, the system will ask for the number of the port to whic h you want to conne ct (1 to 2 or 1 to 4). Type in the number of the port desired. If a number higher tha n the possible number of available ports is chosen (e.g., 9), the system will automatically select port 1 on the destinati on user car d.

Note: The serv setting is not available for the HSU-T V11 and HSU-T 35 Cards.

MODE

The Mode paramet er appears only for the HSU-T V11 and HSU-T 35 Cards. It allows you to identify how the HSU port appears to the devic e on the other end of the interface cable. The dce option causes the port to be recognized as a DCE (data circuit-ter minating equipment) device. The dte option causes the port to be recognized as a DTE (data terminal equipment) device.

Note that th e choices appea ring for s ome of the parameters that follow will depend on whe ther you choose dce or dte as the Mode. Those parameters and their available settings are described below.

Figure 1- 9 shows the display when table is selected. Using the space bar to select and desele ct the time slot, this example shows time slots 1 1 to 16 on WAN 1-1 assigned to this port. The time slot assignments do not have to be contiguous on any card por t.

Note: Do not change this parameter when the HSU Car d is linked to an ISDN-PRI

connection.

RATE

The Rate setting all ows you to select the band width for all time slo ts assigned to th is port. The available opt io ns are 56k or 64k. This selection is multiplied by the number of time slots assigned to the port, to define the ove rall port speed. For example, if you choose 64k as the port Rate and assign four time slots to that port, the overall port speed is 256 kbps.

Tx CLOCK

The Transmi t Clock (Tx CLOCK) setting identifies the clock source for the SD (send data) signal from the external CPE. The int (internal) setting requires an external DTE to synchronize its tran smitted data with the clock on the SCT leads. The ext (extended) setting requires the DTE to synchronize its transmitted data with the clock on the SCTE leads.

Use ext with a l ong cable run t o ensur e th e dat a and clock a re in- phase when th ey arr ive at the system. The DTE must loop back the clock on the SCT leads to the SCTE leads.

If ext is select ed but the system does not detect an incoming c lock on the SCTE leads, the HSU Card automatically gene rate s an internal clock. If this clock is not synchronized with the incoming data, reset the CLOCK PLRTY option to synchronize the clock and data. The Tx CLOCK PLRTY option settings are described in the next paragraphs.

On the HSU-T V11, HSU-T 35 and HSU* 4E 530/35 SS Cards, the T ransmi t Clock option can be set only if the Mode for the card port is set to dce. The default TX Clock setting in the dce mode is int. For a dte port, the only available setti ng is n/a.

Tx CLOCK PLRTY (821660 card)

The Transmi t Clock Polarity (Tx CLOCK PLRTY) setting provides another way to compensate for long c ables in th ose cases where the DTE equipmen t does not p rovide SCTE. When you choose inv (inverted mode), the r elationship between the clock and data is altered to compensate f or long cable r uns that th e data signa ls must trav erse between the card por t and CPE. When you choose norm (normal), the relationship between the clock and data is unchanged. If you use inv, set the Tx CLK (Transmit Clock) option above to int (internal).

On the HSU-T V11, HSU-T 35 and HSU*4E 530/35 SS Cards, the Clock Polarity setting above can be set on ly if the port Mode is set t o dce. The default setting in that node is norm. For a dte port, the only available setting is n/a.

DATA PLRTY

The Data Polar ity (DAT A PLR TY) opt ion allows you to eithe r send all data bits to t he networ k as normal ones and zeros, or to invert all bits in the transmitted data stream. Choose norm (normal) to leave the transmi tte d data intact; or, ch oose inv (inverted) to invert all outgoing data. This can be helpf ul in ensuring m inimum-one s densi ty tra nsmission over T1 links whe n

the data contains long stri ngs of zeros. Inverting the zeros reduces the like lihood that the composite T1 stream will not meet minimum-one s densit y require ments. Bot h systems of t he end-to-end HSD circuit path require the same DATA PLRTY option setting.

Model No.

CTS

The Clear To Send (CTS) setting controls when data is sent. Some DTE equipment must receive a CTS signal before transmitting data. Set the CTS option to perm (permanent) t o make CTS permanent ly High (asse rted). Choose rlocal (remote-loc al) to allow R TS to control both CTS on the local DTE device and RLSD on the remote DTE device.

Choose to ignor (ignore) to always force CTS Low (negated). Set the CTS option to locl (local) to make CTS follow RTS from the local DTE.

On the HSU-T V11 and HSU-T 35 Cards, the CTS settings are used only if the port Mode is set to dce. The default setting in that mode is perm. For a dte port, the only available setting is n/a.

CTS DELAY

The Clear To Send (CTS) Delay setting delays changes in the CTS signal in the local mode. Enter the value you need in millisec onds. The available options are 0, 30, 60, and 100 ms. If you do not know what value you ne ed, s tart with 0 (z ero) ms and i ncreas e the value gr adua lly until you no longer e xper ience problems. The CTS opti on above m ust be set to locl before the CTS DELAY setting has any effe ct.

On the HSU-T V11 and HSU-T 35 Cards, the CTS Delay settings are used only if the port Mode is set to dce. The default setting in that mode is 0 (zero). For a dte port, the only available setting is n/a.

LOCAL LB

The Local Loopback (LOCAL LB) option activates a loop back on the selected card port. Choose the dte setting to loop the outgoing data from the external DTE device back to the DTE receiver . This loopba ck (see Figure 1-10) allows you to check the loca l cabling and most of the circuitry in the HSU Card. It also disconnects the incoming data from the far end.
