Alcatel‑Lucent AKM70 S1‑7 SMUX1 Sub‑Multiplexer – T3PQWAEAAH
The Alcatel‑Lucent AKM70 S1‑7 SMUX1 is a highly versatile sub‑multiplexer tributary module, identified by the hardware code T3PQWAEAAH. This card functions as an access interface for the AKM70 series multiplexer platforms, aggregating low‑speed electrical and optical tributary signals – such as E1 (2.048 Mbps) and T1 (1.544 Mbps) – into a higher‑rate aggregate stream for backhaul over metropolitan or access networks.
Product Overview
The AKM70 is a compact, modular multiplexer widely used for edge aggregation and customer premises equipment (CPE). The SMUX1 sub‑module, installed in slot S1‑7 of the host chassis, provides a flexible interface for connecting legacy time‑division multiplexing (TDM) equipment. It supports both balanced and unbalanced electrical interfaces, as well as optional fiber optic connectivity for remote sites.
The T3PQWAEAAH variant includes an enhanced serial interface with advanced jitter reduction and over‑voltage protection, making it suitable for long‑reach copper applications. Its hot‑swappable design allows field upgrades without disrupting other services.

Key Features
High port density for connecting multiple PBX, router, and legacy voice gateways.
Programmable gain and line equalization for extended copper reach up to 2 km.
Remote loopback and diagnostics for each tributary port.
Integrated performance monitoring with errored second counts.
Priority queuing for delay‑sensitive voice traffic.
Redundant power paths for increased resilience.
Deployment Scenarios
This module is typically installed in enterprise branch offices where it aggregates E1/T1 circuits from legacy PBX systems and maps them into Ethernet traffic for connectivity to a corporate WAN or IP‑MPLS core. In service provider networks, it serves as the demarcation point for leased line services, allowing the operator to monitor and test line quality remotely.
The ability to mix electrical and optical interfaces makes it suitable for hybrid campus environments with both copper and fiber distribution.
Management and Integration
The AKM70 SMUX1 is managed via the host system's SNMP agent or a local CLI. It exposes a detailed management information base (MIB) for each port, allowing fault and performance management per circuit. The module supports in‑service software upgrades and can be configured using a web‑based interface.
Reliability
The module is designed with derated components and features a typical MTBF of 180,000 hours. It meets ETSI environmental standards for temperature and humidity.
Conclusion
The Alcatel‑Lucent AKM70 S1‑7 SMUX1 (T3PQWAEAAH) is a flexible, high‑density solution for TDM aggregation and conversion. Its robust design and extensive diagnostics make it an excellent choice for bridging legacy and next‑generation networks.
