h1. Cisco AS5400
This is a modular access server for voice, data (ISDN) and modem calls. It has a modular archticture and there are a variety of suitable modules.
The System consists of a Mainboard, a backplane and three trays. Each of the three Trays can house two modules.

h2. Trays
The tray has one connection to the backplane, and two proprietary high-density connectors for the two modules.
The central TDM component on the Tray is the Zarlink *MT90866* _2432x2432 non-blocking digital switch with H.110 interface_ (data sheet see attachment:MT90866.pdf. attachment:MT90866.pdf
Each module's PCI bus is bridged to the backplane PCI using a Pericum *PI7C8150* _2-port PCI-to-PCI Bridge_ (data sheet see attachment:PI7C8150.pdf)
h2. Modem modules
h3. NP108 module
This module is built around 18x Conexant/Mindspeed *RL56CSMV/6* chips (data sheet see attachment:RL56CSMV_6.pdf). Each of the chips features its own *MT48LC4M16A2* RAM chip. Internally, each of those chips contains an _ARM core_ for management, and six _Digital Data Pump_ dies.
Interfacing with the backplane is done via 3x Intel i960.
h3. NP60 module
This module is the little brother of the NP108. It is built around 10x Conexant/Mindspeed *RL56CSMV/6* chips (data sheet see attachment:RL56CSMV_6.pdf). Each of the chips features its own *MT48LC4M16A2* RAM chip. Internally, each of those chips contains an _ARM core_ for management, and six _Digital Data Pump_ dies.
Interfacing with the backplane is done via 2x Intel i960.
h2. Trunk interface modules
h3. 8PRI
This is an 8x PRI (E1/T1) interface.
Each PRI interface has its own EMI / overvoltage / transforer section, followed by a Mindspeed *Bt8370KPF* E1/Ta transceiver (datasheet see attachment:Bt8370KPF.pdf). The main CPU is an MPC860 PowerPC, interfaced via a PLX *PCI9054* PCI bridge (datasheet see attachment:PCI9054.pdf).
There are also two PMC FREEDM8 *PM7366* _Eight Channel Frame Engine and Datalink Manager_ (datasheet see attachment:PM7366.pdf).
