What does STS12 (signal) represent?

STS-12 (Synchronous Transport Signal level 12) is a SONET transport signal with a synchronous line rate of 622.08 Mbit/s used in fiber optic networks.

How is ISDN (dual channel) defined in this context?

ISDN (dual channel) uses two 64 kbit/s bearer channels in parallel to deliver an approximate combined data rate of 128 kbit/s.

Why convert STS12 (signal) to ISDN (dual channel)?

Converting helps network engineers relate high-speed backbone transport rates to smaller bonded telecommunication channel capacities for planning and interfacing network segments.

Common Use Cases

Carrier and ISP backbone or metro fiber link capacity planning
Relating SONET infrastructure rates to ISDN bond channel data throughput
Designing backup or remote LAN access links using ISDN dual channel
Configuring SONET ring architectures with consideration of legacy ISDN services

Tips & Best Practices

Use this tool to conceptually relate SONET rates to ISDN equivalents rather than for precise physical layer calculations
Consider network overhead and signaling factors when planning real-world throughput
Verify conversions align with your network architecture and service requirements
Utilize example conversions to understand scaling between high-capacity and bonded channel rates

Limitations

ISDN (dual channel) denotes combined bonded channel throughput, not a strict physical data rate
Conversion is primarily conceptual given ISDN use at STS12 scales is rare
Assumes ideal channel bonding without factoring overhead or inefficiencies
Does not replace detailed network performance testing or protocol analysis
