If there are any outboard electronic packages

mounted beside the AT&T 881B station protector,
they may have to be moved. The tii 759 Series

After ensuring that adequate space is available to

mount the tii 759 Adapter, remove and discard
the 8813B cover.

designed to retrofit either one pair or two pair
station protector housed in an AT&T 8813B
Service Enclosure.

The tii 759 1 is furnished complete with

customer wiring bridge / RJ-11 modular jack with
spade tipped leads for one pair. The tii 759 2 is
similarly equipped for two pair.

No special tools are required to install or

maintain this product.

The tii 759 is equipped with a cover tab that

allows the customer to lock the unit, but allows
the Telco to override the lock.

The interior has a set of hinged covers that keep

the Telco protector modules and station

electronics out of the customer’s view and touch.

They may be accessed with a 3/

” hex head

8

terminal wrench or a pin-in-head wrench.

The customer wiring bridge and the RJ-11

modular jack are press fit and readily field
replaceable.

The tii 759 Series Universal Network Adapter is

equipped with four card slots which allow a
variety of station electronics to be fitted to the
customer line.

If the hook up wire or OSP cable is physically

larger than No. 22AWG, a fusing conductor of
No. 22AWG solid copper wire with thermoplastic
insulation or No. 22AWG copper clad steel
(bridle wire) shall be employed.
