Edit the Clock Source, Internal Clock Speed, Sync Line Coding, Cable

Type, and RTS Enable parameters, described next:

Parameter: Clock Source

Default: Internal

Options: External

Internal

Function: Identifies whether the router provides clocking to (Internal) or receives

clocking from (External) the other device. The parameter specifies the

origin of the synchronous timing signals. If you set this parameter to

Internal, this router supplies the required timing signals. If you set this

parameter to External, an external network device supplies the required

timing signals.

Instructions: For direct connection to a control unit, such as an IBM 3174, set to

Internal. For connection to a modem, set to External. For direct

connection to an IBM 3745, either the router or the IBM 3745 can provide

the clock source. If the IBM 3745 does not provide clocking, set to

Internal.

MIB Object ID: 1.3.6.1.4.1.18.3.4.5.1.13

Note:

When connecting the router directly to an SNA endstation, the cables

connecting these devices must connect the “transmit” pins of one device to the

“receive” pins of the other. Typically, a DCE cable for the SNA equipment has

a male interface and is connected to a Bay Networks synchronous

pass-through cable with a female interface. Refer to Appendix C

for more

information about cables.
