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.
