10.1 DIGITAL TRUNK INTERFACE CARD (DTIC) OVERVIEW
The DTIC is applicable only to specific Octel channels
in Europe and is available only through those channels.
This chapter contains information specific to the digital trunk interface card (DTIC). Included are details
about hardware, installation, configuration, and maintenance and troubleshooting. The DTIC is not
documented elsewhere in this manual.
The DTIC is a 30-port line card designed to interface an Octel Overture 200/300 to E1 trunks.
E1 trunks are the European “building block” standard for Wide Area Network (WAN) communication.
E1 is specified by CCITT and also standardized by ETSI. An E1 trunk can carry 30 simultaneous phone
calls plus signaling information. A port carries voice and data for calls. Each port can be viewed as a
“virtual” telephone connection where each end is either on hook or off hook.
For the DTIC to operate correctly, two tables must be configured in the Octel Overture 200/300: the
SLOTS Table and the SYSTEM PARAMETER Table. An LSP Table is also used by the Octel Overture
200/300. A COS must be configured for each of the 30 DTIC ports.
DTIC Hardware
The DTIC consists of two major processing components: the control processor (CP) and five digital
signal processors (DSPs). Refer to Figure 10-1 showing the layout of the primary components on the
card.
To connect the Octel Overture 200/300 to the PBX, use two 75-ohm coax cables. Be sure that the sw1
and sw2 switches on the card are set correctly to 75 ohms and 120 ohms for Germany. Refer to
Figure 10-1.
