What does STS3c (payload) represent?

STS3c (payload) is the concatenated SONET payload container providing a high-bandwidth optical transport channel with data rates around 155.52 Mbps.

How is ISDN (dual channel) defined?

ISDN (dual channel) uses two bonded 64 kbit/s B channels from an ISDN Basic Rate Interface to provide a combined data throughput near 128 kbit/s.

Why convert between STS3c (payload) and ISDN (dual channel)?

Conversion helps compare high-capacity optical network speeds to smaller ISDN configurations for network planning, upgrade decisions, and bandwidth understanding.

Tips & Best Practices

Always consider that ISDN (dual channel) is a service-level descriptor, not a strict SI unit
Use the conversion results for planning rather than direct data substitution
Account for protocol overhead and framing when interpreting bandwidth equivalencies
Apply conversions within telecommunications and network engineering scenarios for best relevance

Limitations

ISDN (dual channel) represents a telecommunication configuration rather than an exact unit of measurement
Conversion reflects approximate equivalencies due to protocol and payload overhead differences
Direct substitution is impractical because ISDN dual channel speeds are much lower than STS3c throughput
Effective bandwidth may vary depending on framing and overhead not accounted for in simple conversion
