Upon initial installation, the OCM uses factory default settings. To provision the OCM, connect a
terminal emulator via the RS-232 (DB-9) connector on the front panel. The terminal must be VT100
compatible and set for 9600 bps, 8 data bits, no parity and 1 stop bit. The following table lists the
provisioning settings and their default values. The settings are retained in a nonvolatile memory device
in case of power loss to the OCM.

The online unit's provisioning settings are written to the standby unit. Linked Provisioning is always enabled.

Back-to-Back Mode
Back-to-Back mode is used when OCMs are connected together in a point-to-point setup. It consists of one OCM
configured for Central Office and the other for Remote. This mode of operation supports accessing the remote OCM
menus, either by the CO craft port or the CO Ethernet LAN (via Telnet). This remote management is carried over the
DCC section on the fibers between the OCMs. This mode of operation supports remote management of other ADTRAN
equipment subtended from the OCM at the remote site. TFTP and SNMP are supported in this mode, both on a local
Ethernet access and to the remote OCM. NMA access is supported with TL1 via Telnet, where NMA can access both
devices via the CO TL1 session (CO acts as GNE, 1 IP address assigned).
2.
Subtended Mode
The OCM functions as a full SONET terminal multiplexer in a new or existing SONET network. It consists of one OCM
configured for Subtended mode. This mode allows each OCM to directly connect to SONET backbone equipment.
Management access is also provided over the DCC to other network elements on the SONET ring. The DCC Interface
must be properly configured, LAPD parameters and NSAP Area Address, for the SONET network for remote OCM
management. The OCM can be also used as a GNE device to allow TL1 access to the existing SONET network.

NOTE: Refer to the Installation and Maintenance Practice (P/N 61184002L3-5) for details and options.
Software downloads for the local OCM are provided using TFTP , XModem, and YModem protocols in any DCC mode. Software
downloads to the remote OCM through the CO OCM is only supported in a Back-to-Back mode. TFTP downloads are provid-
ed through the Ethernet interface (provided through the rear of the chassis) or over the DCC channel (TFTP over DCC channel
only provided when configured for Back-to-Back mode). XModem and YModem downloads are provided through the craft
port and Telnet connections.
WARNING: The 10/100baseT interface and DS3 interfaces MUST NOT be
metallically connected to interfaces which connect to the Outside Plant
or its wiring. These interfaces are designed for use as intra-building interfaces only. The addition of Primary Protectors is
not sufficient protection in order to connect these interfaces metallically to OSP wiring.
