Control Interface
This unit is managed through the craft port, the Network Management Software (NMS), or an SNMP Network
Node Manager (NNM) which controls the provisioning of the unit and obtains status information from the unit.
Provisioning is described in the Optioning section of this document. For operation, see the craft port, NMS or
NNM documentation.
This unit will maintain its default provisioning until that provisioning is altered through the control interface. If this
unit’s provisioning is changed, it will maintain the new provisioning even if power is lost. If replaced with a new
unit, the new unit will default to the same provisioning as was set for the prior unit. If this unit is installed in a loca-
tion that was used by a different type of unit, such as a 6 channel half size card, it will use its own default provi-
sioning.

INSPECTION
2.1
Inspect for Damages
Inspect the equipment thoroughly upon delivery. If the equipment has been damaged in transit, immediately re-
port the extent of damage to the transportation company.
2.2
Equipment Identification
Charles Industries’ equipment is identified by a model and issue number imprinted on the front panel or located
elsewhere on the equipment. Each time a major engineering design change is made on the equipment, the issue
number is advanced by 1 and imprinted on subsequent units manufactured. Therefore, be sure to include both
the model number and its issue number when making inquiries about the equipment.
2.3
Static Concerns
Each unit is shipped in static-protective packaging to prevent damages from electrostatic charges. Use approved
static-preventive measures, such as static-conductive wrist straps and a static-dissipative mat, when handling
units outside of their protective packaging. A unit intended for future use should be tested as soon as possible
and returned to its original protective packaging for storage.
