Quick-Start Programming
Before You Begin
Before you begin programming, you should be familiar with resetting the
DBS and performing the "New Function Reset" command. The following
paragraphs explain when these two procedures are used.
The New Function Reset command. If you are installing T1 while you're
upgrading to a new DBS release, perform the "New Function Reset" before
you begin T1 programming.
You must perform the reset command if you're upgrading to a completely
new release, but not if you're upgrading to a point release. For example, if
you're upgrading from Version 3.10 to Version 4.00, you need to perform the
reset. However, if you're upgrading to a point release (4.06 to 4.07), you do
not need to perform the reset.
Manually Resetting the DBS. Many of the T1 programs require a manual
reset to take effect. Program all of the quick-start items first, then reset the
system by powering it off then back on. (DO NOT RAM CLEAR!)
Hardware Setup
1. Install the T1 interface in each DBS using the Installation Procedures
2. If no networked DBS has a T1 that connects to the public network, choose
3. For every direct connection between two networked DBS systems (i.e.
DBS-2.3/9.2-540
described in Section 500 - T1 Reference Manual.
Note: The DBS T1 Trunk Card (VB-43561) must contain COP Version
2.0 or later.
one networked DBS as the clock source and strap its Sync Unit CN4
connector to Free Run. Strap all other DBS systems to Net. If an external
sync source clock is available, strap all DBS systems to Net.
For example, if two networked DBS systems are directly connected and no
other T1 is present, one of the systems must supply the sync clock and be
strapped for Free Run. However, if at least one of the systems has a T1
connection to the public network, this should be used to supply the sync
source clock.
Note: See "Sync Source Examples" on page 129 for more information.
