Make SIP Connections for Data Terminals and Computers

Any RS-232C compatible data terminal, personal computer host computer, or a STAR LAN NETWORK workstation can be connected in one of four ways:

●If the terminal has a modem, it should be connected to a ZTN78 CP in the same way as a single-line voice terminal.

●The terminal’s RS-232C port may be connected to an Asynchronous Data Unit (ADU) and then to the SIP over standard building wiring. Use an octopus cable to connect the SIP appearance to a TN726 CP.

●The terminal may be linked to a voice terminal at the workstation via an ADU and connected to the SIP using the same cable run as the associated voice terminal. (See Note below.)

●A STARLAN NETWORK workstation equipped with a Network Access Unit (NAU) may be linked to a voice terminal and connected to the SIP using the same cable run as the associated voice terminal. This arrangement is described under Install STARLAN NETWORK Interface. (see Note.)

Note: MET sets cannot share the cable run with an ADU. Use separate 4-pair cable runs for the MET set and ADU. The 7300H Series voice terminals that share a cable run with an ADU require local power.

The installation procedure for the last two types of connections listed is as follows:

1.Determine the type of connection required for each data terminal and computer from the Voice and Data Station Records Form (Figure 2- 26).

2.At the SIP, identify all wiring for voice/data connections. Remove the octopus cable plug (if already inserted for a voice terminal). Insert a WP90851, L1 Y adapter into each of the adapter jacks. Re-insert the (voice circuit) octopus cable plug into the voice side of the Y adapter.

3.For STARLAN NETWORK workstations, connect the data side of the Y adapters to IN jacks on a STARLAN NETWORK Network Extension Unit (NEU). For all other terminals, connect TN726 CP ports to the data side of the Y adapters (or to standard SIP adapter jacks for data-only connections) with an appropriately labeled octopus cable.
