Strata AirLink Systems
Do not install the wireless equipment on public coin service provided by the telephone company. 
Connection to party line service is subject to state tariffs. Contact the state public utilities 
commission for information.
It is recommended that an AC surge arrestor be installed in the AC outlet to which the wireless 
system is connected. This prevents damage to the equipment caused by local lightning strikes and 
other electrical surges.
The wireless system provides access to interstate providers of operator services through the use of 
equal access codes. Modifications by aggregators to alter these capabilities is a violation of the 
telephone operator consumer services improvement act of 1990 and Part 68 of the FCC Rules.
Part 15
This equipment has been tested and found to comply with the limits for a Class A digital device, 
pursuant to Part 15 of the FCC Rules. These limits provide reasonable protection against harmful 
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in 
accordance with this chapter of the Strata DK Installation and Maintenance Manual, it can cause 
harmful interference to radio communications.
Important!
lChanges or modifications not expressly approved by Toshiba America Information 
Systems, Inc. can void the authority to operate the equipment.
lThe 25-pair cable that connects the BSIA to an MDF must be shielded to meet FCC 
emissions limits under Part 15 Class A.
UTAM, Inc.
The Strata AirLink system operates in the 1920~1930MHz band, and microwave services are also 
offered in this band. The FCC has designated UTAM, Inc. to coordinate the transition of 
microwave services to other frequency bands and the installation of new UPCS equipment, which 
includes the wireless system, until all microwave users are cleared from the band.
Each device requesting FCC certification must have an affidavit from UTAM stating that the 
device meets the requirements of Rules 15.307(d), (e), and (h), regarding UTAM location 
verification and disablement. The basic mandatory requirements are:
©The handset must not transmit when it is not within the coverage area of any system Base 
Station.
©A Base Station must not begin operation until it is UTAM confirmed and attached to a 
permanent structure such as a building so that it cannot be easily relocated.
©If the system is removed from its original installed location and re-installed at another 
location, the system must not begin operation until the new location is UTAM confirmed.
The Frequency Coordination Service Request (sample on Page 16-90) must be completed and sent 
to UTAM before activation of the system. Contact the Strata AirLink Desk at (949) 598-4980 for 
more information between the hours of 8:00 a.m. and 5:00 p.m. (Pacific Standard Time), Monday 
through Friday. Voice mail is available for messages after hours.

To ensure that installations are fully protected from fire hazards, UL1459 specifies primary and 
secondary protectors for circuits that interconnect to the telephone network or cables that exit/enter 
buildings.
Primary and Secondary Protectors
Protectors replace bridge clips when installed across two horizontal 66-block terminals. When 
using 66-50 connector blocks, it is recommended that protector ITW Linx SCP-9 be used as the 
secondary protector and out-of-building primary protector. It provides overvoltage protection of 
600VAC or DC, overcurrent protection of 350 mA, and installs in series with the telephone loop.
Line circuits do not require protectors unless the circuit is cross-connected to out-of-building 
circuits. In this case, it is recommended that ONEAC 6-AP200 protectors are used. This is a single, 
block-mounted protector that provides both primary and secondary protection for out-of-building, 
single-line circuits.
System Line Circuit Requirements
Line circuits do not require protectors unless the circuit is cross-connected to out-of-building 
circuits. Out-of-building circuits require primary/secondary protectors, and it is recommended that 
the ONEAC 6-AP200 be used. This is a single, block-mounted protector that provides both 
primary and secondary protection for out-of-building, single-line circuits that are terminated to a 
system.
