UTP: Unshielded Twisted Paired

1,2,3,6 is used

(Hub <-> PC) Device port label different 1 and 1x

Straight line(Both Ports): Brown, Brown white, Green, Blue white, Blue, Green white, Orange, Orange white

(Hub <-> Hub, PC <-> PC) Device port label same 1x and 1x or 1 and 1

Cross Line:

1. Brown, Brown white, Green, Blue white, Blue, Green white, Orange, Orange white

2. Brown, Brown white, Orange, Blue white, Blue, Orange white, Green, Green white

WAN Responsibility Seperation

DTE: Data Terminal Equipment (User end last device)

DCE: Data Communications Equipment (Service provider end last device, provide the time service)

Network Transport: Serial mode, No parallel mode

Experiment Environment

Only got DTE devices without DCE devices.  Connect the two DTE device directly.

Use command(clock rate) in one DTE port to simulate DCE device.

Ports in Router 2503(Solidify)

AUT PORT (DB-15) --> Ethernet

two Sync. serial ports(DB-60) --> WAN

ISDN BRI PORT (RJ-45) --> Dial

Console Port(RJ-45) --> Local Control Port

AUXLIARY PORT(RJ-45) --> Remote Control Port

Ports in Router 1603(Modularization) Reduce cost

ISDN Ports(left -> right)

Ethernet Port(RJ-45) (low voltage)

ISDN BRI Port(RJ-45) (high voltage)

Console Port(RJ-45)

Console Port Connect to PC

Line: RJ-45 <-> DB-9

Normal Communication Port Setting: 9600/8/no/1/no

Transport System to Router Communication Port Setting: >9600/8/no/1/no
