This section provides information to help determine your AS2000
configuration, and includes site planning and node configuration
worksheets. Examples of worksheets filled out before hardware
installation and software configuration are also shown.
Pre-installation
Questionnaire
The pre-installation questionnaire provides critical need-to-know
information before AS2000 installation and configuration. Cabling
distances are critical.
• T1 line framing: ESF or SF (D4).

• T1/E1 line fractional: yes or no.
If yes, which DS0s (Level 0 channels) are assigned?
• Is the T1/E1 installed and tested end to end?
• Distance from the T1/E1 demarcation to the AS2000.
• Distance from the AS2000 to the DTE devices.
• Type of DTE interface (RS–232, RS–449, V.35, EIA 530, X.21,
HSSI).

Is DTE equipment part of a tail circuit? yes or no.
• Expected DTE data rate (kbit/s, Mbit/s).

mounting location?
• What are the desired timing sources?
