Figure 2. OnSite Model 1063
The OS1052 and OS1063 systems have two expansion slots. The expansion slots support the insertion of the
following modules for flexible configuration changes and capacity upgrades:
• 21-port E1
• 3-port DS3/E3
• 2-port STM-1 optical and electrical
• 8-port Ethernet 10/100BASE-TX
Figure 3 on page 17 shows the front and back panels of the OS1052 base system without the expansion mod-
ules installed. The OS1052 has eight built-in E1 and two built-in Ethernet 10/100BASE-TX interfaces. As a
factory-installed option, the OS1052 is also available with eight T1 ports. The OS1052 uses a future bus con-
nector for access to the 8 E1 or T1 ports on the base system.
