USER’S GUIDE
244 CyberSWITCH
To define a Dedicated Access, you must select a previously defined line. Then, input the details
required to use the line.
Notes: To achieve maximum bandwidth, you could theoretically dedicate two T1s to one remote
device (3072 Kbps). Any configuration above this maximum bandwidth is not supported.
Keep in mind that you can aggregate a maximum of 32 connections. These connections can
be any combination of dedicated and/or switched connections to the same device. For
maximum performance, however, we recommend aggregating no more than eight
connections at a time.
X.25 A CCESSES
C ONFIGURING AN X.25 A CCESS
Note the following:
•
X.25 accesses are available only if you have purchased the additional software module for
packet switched accesses. X.25 is not available on CSX158 platforms.
• To establish virtual circuits over X.25, you must enable device level security ( page 167 ).
• You may only configure one X.25 access per CyberSWITCH, and one line per access.
• Bearer channels used by X.25 accesses can not be shared by other access types.
• Compression is not available over X.25 connections.
U SING CFGEDIT
To add an X.25 access, several categories of information must be configured, including basic
configuration information including line information, Link Access Procedure Balanced (LAPB)
parameters, X.25 parameters, and finally, virtual circuit parameters. A separate section for
configuring each of the above categories follows.
Notes: If you are unsure of a value, select the default value if one is provided. If you want to
change an existing X.25 access configuration, select the “change” option from the main X.25
Access menu. A submenu will display the various categories described below. You can
then select to edit individual categories without paging through all of the parameters. It is
important to note that the line used for an existing X.25 access cannot be changed.
Individual characteristics of the line can change, for example, the data rate, bearers, or
Public Packet Switched Network (PPSN) phone number. If another line is to be used, the
existing access must be deleted, and added back in.
B ASIC C ONFIGURATION I NFORMATION
1. Select Access from the Physical Resources menu, then follow the onscreen instructions to add
an X.25 access.
2. Select the line Id this access will be using. A BRI line that is in use by another type of access will
not be available for use by an X.25 access.
3. Enter an X.25 access name of 1 to 16 non-blank, alpha-numeric characters. The X.25 access name
is a user-defined name and is provided as an aid in helping you track events occurring on an
X.25 access.
