STM-1 (signal) to ISDN (dual channel)
Please provide values below to convert STM-1 (signal) to ISDN (dual channel), or change ↔.
STM-1 (signal)
Definition: STM-1 (signal) refers to the base signal in SDH (Synchronous Digital Hierarchy), with a transmission rate of 155.52 Mbps, comparable to STS3 in SONET.
Funfact: STM-1 signals are the foundation of SDH networks, similar to STS1 in SONET, and are often used in international communication lines.
ISDN (dual channel)
Definition: Represents a data transfer rate of 128 Kbps using two ISDN channels.
Funfact: Dual ISDN channels were used for faster communication in both voice and data services.

How to Convert STM-1 (signal) to ISDN (dual channel)
1 STM-1 (signal) = 1215 ISDN (dual channel)
1 ISDN (dual channel) = 0.0008230453 STM-1 (signal)
we use cross multiplication method
STM-1 (signal) → ISDN (dual channel)
1 → 1215
1.5 → ?( suppose x)
=>1.5*1215=1*x
by simplifying
x=1822.5
