External connection Specification of Serial Ports on the DI-2006
1. External Connection Specification of Serial port on the DI-2006
The router is connected to synchronous MODEM, asynchronous MODEM or baseband
MODEM supporting the physical protocol of V.28 protocol(or RS232 protocol)
according toFiguer 2-4.
When the serial port is connected to baseband MODEM supporting the physical
protocol of V.35, the connection figure is as Figuer 2-5.
The serial number of V.35 MODEM cable is DRC4211.
2. External Connection Specification of Console port on the DI-2006
The cable connects the Console port of DI-2006 and external terminal Console devices.
One end is a 8 pin jack, and the other is a 25 aperture connector(DB25) and a 9
aperture connector(DB9). The RJ45 connector is plugged into the Console port of the
router, and among DB25 and DB9, one should be selected according to the
requirement of the terminal serial port. The internal connection of the cable is shown
as Figuer 2-6. The serial number of the Console cable is DRC0001.
3. External Connection Specification of AUI and TP interface on the DI-2006
AUI port is also called thick Ethernet interface, which can connect to the thick cable
with AUI cable. AUI port can also connect to the thin cable, or TP interface, the
Ethernet RJ45 port, through the special switch box.
TP port can connect general five types of twisted pair to HUB. Connect as shown in
Figuer 2-7:
4. External Connection Specification of ISDN S/T Interface on the DI-2006
With straight RJ45 line, network terminal NT1 connects to ISDN BR1 S/T interface.
Straight RJ45 Line is shown as the following figure:
