Enterasys Networks CSX5500 Characteristic PRI/T1 lines E1 line, Multiframe CRC, CommonChannel

USER’S GUIDE

3.Select following line characteristics:

•framing type

•line coding type

•T1 signaling method

If you are unsure of your line's characteristics, try the following defaults:

Characteristic	PRI/T1 lines	E1 line
Framing type	ESF	Multiframe CRC
Line coding type	B8ZS	N/A
Signaling Method	Common_Channel	N/A

4.Select the correct T1 line build out value (US only). If you are using an external CSU, specify a short haul build out (line length in meters). If you do not have an external CSU, specify a long haul build out (decibel attenuation value from Telco).

5.A data link is assigned to the line upon completion of the line configuration. Add more data links or modify the existing data link.

a.Only if you plan on using X.25 over the D-Channel on this line, answer yes to the following prompt:

Will this Data Link support X.25 communications (Y/N)? [default N]

b.Assign a TEI Negotiation value of 0.

Note: If you select E1/R2 signaling for your framing type, you will not be asked to configure datalinks (items 4 and 5). R2 signaling does not make use of a datalink; all datalinks associated with the line are automatically deleted.

If you select a Robbed Bit line, CFGEDIT will inform you that RBS will delete any datalinks on the line. The system will prompt you to confirm this deletion, and then automatically delete the datalinks.

CONFIGURING A LINE FOR V.35 AND RS232 RESOURCES

1.Enter the line name.

2.Select the line’s slot and port combination.

3.Select the line type.

Note: The network line type is designated for lines used by a Dedicated Access, Frame Relay Access, or X.25 Access.

4.Select the data line idle character. The default value is marks. However, there may be some receiving devices which cannot properly make this determination with the default of idle marks. If communication cannot be established with the receiving device, you may need to take
