Figure 2 shows the front panel of the OS1063 system. The OS1063 uses a future bus connector for access to
the 21 E1 or T1 ports on the base system. When the system is equipped with two 21-port high-density E1
(HD-E1) expansion modules, the OS1063 provides access for up to 63 E1 ports. (See chapter 12 for a descrip-
tion of the future bus connector and the features of the high-density E1 expansion module.) As a factory-
installed option, the OS1063 is available with two STM-1 electrical interface (STM-1e) ports on the base sys-
tem.
