Caution: When a T1/E1 ASAP Adapter card port that is configured for T1 is connected to
external equipment or is in physical loopback, ensure that the external equipment's transmit
signal is attenuated according to the distance to the T1/E1 ASAP Adapter card receiver.
Adjust LBO settings appropriately so that the T1/E1 ASAP Adapter card receiver's nominal
input voltage level is < 3Vp. Refer to "Configuring DS1 Line Buildout" in the 7705 SAR OS
Interface Configuration Guide for detailed information on attenuating transmit signals.

Electrostatic discharge (ESD) damage can occur if adapter cards are mishandled. Always
wear an ESD-preventive wrist or ankle strap connected to a nearby ground point that is
connected to the site grounding point (typically, the grounding stud on the 7705 SAR-8 or
7705 SAR-18, or a properly grounded rack or work bench).
Always place components on an anti-static surface.
Do not power up a 7705 SAR-8 or 7705 SAR-18 before verifying that all common
equipment (chassis, power, cooling, and grounding) is connected properly.
The Fan module and all cards in the 7705 SAR-8 chassis must have the same voltage
type.
Filler plates are required in all empty slots to prevent excess dust accumulation and to help
control airflow and electromagnetic interference.
To comply with the GR-1089-CORE requirement R4-9 [31] standard for electromagnetic
compatibility and safety, all intra-building ports are specified for use with shielded and
grounded cables at both ends.
The intra-building port(s) of the equipment or sub-assembly is suitable for connection to
intra-building or unexposed wiring or cabling only. The intra-building port(s) of the
equipment or sub-assembly must not be metallically connected to interfaces that connect
to the Outside Plant (OSP) or its wiring. These interfaces are designed for use as intra-
building interfaces only (Type 2 ports as described in GR-1089-CORE) and require
isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
Ports cannot be configured until the adapter card is provisioned.
Services cannot be configured until the ports are configured.
Adapter card slot numbers are MDA 1 through MDA 6 on the 7705 SAR-8 and MDA 1
through MDA 12 on the 7705 SAR-18.
T1/DS1 terminations support 100Ω impedance; E1 terminations support 75Ω and
120Ω termination impedances.
