SDH terminal multiplexers: Description of the functions, layout and capabilities of typical STM-1
, STM-4, STM-1
6 and STM-64 terminal multiplex equipment.
Section overheads (SOH): Overview of the purpose of the Section Overhead (SOH) bytes in an STM-1 frame in terms of frame alignment, error checking, data communications
Payload mapping: The location of a VC-4's pointer in the Section Overhead (SOH) of an STM-1 frame
TU payloads: Mapping 34 Mbit/s signals into an STM-1 frame
description of the use of TU-12s, TUG-2s and TUG-3s to map up to sixty-three 2 Mbit/s signals into a single 155 Mbit/s STM-1 frame
transporting groups of CEPT and ANSI signals within the same STM-1 frame
The Mini-Mux 840 is ideal for mass termination of OC-3 or STM-1
signals, highly efficient intra-office transport of T1/E1s, wireless cell site interconnects, or backhaul of legacy DLCs.
As planned, Golden Telecom increased its international IP capacity by two STM-1
channels of 155 Mbps each, raising the aggregate international IP capacity to 1.
