Interoperability with BTI7000 Series Network Elements
BTI7800 Series network elements can be used to aggregate and transport traffic from BTI7000 Series equipment. Client traffic from a BTI7000 Series shelf can be carried seamlessly across a BTI7800 Series backbone network over 10-Gbps and 100-Gbps links. In some configurations, a client on a BTI7000 Series network element can interwork with a client on a BTI7800 Series network element.
Interoperability can be divided into two broad areas: interconnectivity and interworking.
Interconnectivity, in the context of this section, refers to direct physical connectivity between a BTI7800 Series and a BTI7000 Series network element, usually on the line (WAN) side. Interconnectivity relates to compatibility of the protocols, mappings, maintenance signals, and other attributes that govern how two network elements communicate with each other across a fiber. This is the most basic form of interoperability, the ability to connect a fiber from one type of equipment to another.
Interworking refers to logical connectivity, usually between a client on a BTI7800 Series network element and a client on a BTI7000 Series network element. Interworking relates to the compatibility of the service being offered. In addition to the attributes that govern interconnectivity, interworking includes service-level attributes such as client protection, FPSD, PMs, and other end-to-end features.
Interoperability with BTI7000 Series Transponders
The BTI7800 Series can interoperate with the BTI7000 Series dual 10-Gbps transponders (BT7A49AA and BT7A49AA-I02).
This includes both interconnectivity and interworking:
interconnecting a BTI7800 Series device with the line side of a BTI7000 Series transponder
interworking between a client on a BTI7800 Series device with a client on a BTI7000 Series transponder
Client and line designations on the BTI7800 Series equipment are conceptual only. Unlike the BTI7000 Series transponders, there are no fixed client/line ports.
PRBS interworking between a BTI7800 and a BTI7000 Series transponder is not supported. The BTI7000 Series transponder cannot loop back the injected BTI7800 PRBS signal.
Interoperability with BTI7000 Series Transponders in a Bookended Configuration
BTI7000 Series dual 10-Gbps transponders (BT7A49AA and BT7A49AA-I02) can be connected to each other in a bookended configuration across BTI7800 Series equipment.
Not all protocol and line mapping combinations are supported. The main interoperability combinations supported are shown in the following table. The port designations in parentheses correspond to the reference points in the above figure.

Interworking with BTI7000 Series Transponder Clients
BTI7800 Series clients can interwork with BTI7000 Series dual 10-Gbps transponder clients (BT7A49AA and BT7A49AA-I02).
Protection switching (client or line) is not supported in an interworking configuration.
Not all protocol and line mapping combinations are supported. The main interoperability combinations supported are shown in the following table. The port designations in parentheses correspond to the reference points in the above figure.
