OEM - (Original Equipment Manufacturer) - The maker of equipment that is marketed by another vendor, usually under the name of the reseller. The OEM may manufacture certain components, or complete devices, which are then often configured with software and/or other hardware by the reseller.
OEMI - original equipment manufacturer interface
OFC - optical fiber, conductive
Off-net Calls - All calls that are not destined for the backbone network. On standard trunks (other than 56K/64K trunks), calls take up only the bandwidth required for the call itself. These features allow the HDVC to increase the number of voice calls that can be sent and received on trunks by compressing bandwidth. The HDVC module can be used for international applications, because it can convert between Mu-Law and A-Law standards.
Office Channel Unit (OCU) - The DDS module in the Central Office that connects with customer equipment (CSU). It formats customer data into synchronous DS0B-formatted 8-bit bytes and multiplexes them into a 64 kbps signal. This DS0 is then multiplexed into the DS1 signal. The OCU provides test access to the bipolar 64 kbps-formatted signal and responds to OCU loopback requests.

Operator - The person who uses the Operator Interface to manage the network. There are six levels of operators, each with different levels of access to the Operator Interface. The operator is identified by an operator ID of up to eight alphanumeric characters.
Operator Console - The terminal used to communicate with the Operator Interface on the node. Physically connected to the RS-232C interface of the processor module.
Operator ID - Operators are identified in the Operator Interface by a name up to eight alphanumeric characters. The operator name is used to log into the Operator Interface and has session parameters associated with it through the operator profile.
Operator Interface - A menu/query system consisting of four levels: (1) Prolog Procedure menu, (2) Functional Area menu, (3) Action menus, and (4) Object menus.
Operator Profile - A file containing the default session parameters associated with a specific Operator ID and stored in the configuration database. If an operator profile is not updated, changes to the session parameters will be in effect only during the current session. Upon updating an operator profile, the session parameters will be in effect during subsequent sessions under the same operator name.
