Objectives
The S SI pro vides only secondary surge protection for the RGPS and T1/E1 span
connections. The customer is responsible for pro viding primary surge protection.
The objectives of performing T asks 10–13 are as follows:
• Install RGPS cable (AA) between the RGPS cable lightning arrester and the UBS Macro
BTS .
• Install T1/E1 balanced Span I/O cable (W) between the UBS Macro BTS and the site span
line interconnect equipment.
• Install E1 unbalanced Span I/O coaxial cables (customer supplied) between the UBS Macro
BTS and the site span line interconnect equipment.
• Install Customer Alarm Input/Output (IP/OP) cables (X) between the UBS Macro BTS and
the Customer IP/OP interconnect equipment.
