¹ This value indicates the maximum number of pods of this pod type. A single NETLAB_AE system can host up to 10 equipment pods, total.

Lab Topology

Lab Device Requirements

Lab devices are part of the topology and users can interact with them either directly through the console or indirectly via Telnet and other protocols. The Advanced Router Pod includes three routers, R1, R2 and R3. The following table depicts the interface requirements for each router:

Router	Ethernet	Serial	BRI	PRI	AUX/External Modem
R1	1	2	1		1
R2	1	1	Optional	1 (Recommended)	Optional
R3	1	2	1		1

The hardware you select must:

• Be supported by NETLAB_AE.
• Conform to NETLAB_AE router interface naming requirements (see below).
• Meet the specifications for the lab exercises of the curriculums your Academy wishes to implement.

Router Interfaces

The NETLAB_AE interface name translation feature is supported on this pod type. This may influence the selection of modular interface cards and slot placement within the router. Please review the expected interface names for each router.

The Ethernet interface must be a built-in interface, which is capable of activation from the ROM monitor mode. All NETLAB_AE supported routers have at least one Ethernet interface that meets this requirement.

Serial interfaces may be built-in, or provided by modular interface cards such as the WIC-2AS or WIC-2T. Serial connections between routers require the appropriate serial cables. You can use DTE and DCE cables back-to-back, or special cables that provide both DTE and DCE in one cable (available from SIGMAnet).

Be sure to match your router and Adtran Atlas BRI and PRI interface types according to you local requirements (i.e. BRI vs. S/T, T1/PRI vs. E1/PRA).

R1 and R3 communicate with the PSTN using external modems (sold separately).

Adtran Atlas 550 Setup

The Advanced Router Pod utilizes an Adtran Atlas 550 to emulate functions normally obtained from a network service provider. The Atlas 550 is statically configured and always powered on. Lab users do not interact with the Atlas management console.

Slot Configuration

Per the following table, insert the following cards into following Atlas 550 chassis slots.

Slot	Module
SLOT 1	Dual Nx56/64 V.35 Module
SLOT 2	Dual Nx56/64 V.35 Module
SLOT 3	FXS Module
SLOT 4	ISDN BRI Module or S/T Module (as required)
NETWORK 1	ISDN PRI Module

Serial & PVC Setup

Per the following table, connect the router serial interfaces to the Atlas 550 and create 6 permanent virtual circuits using the Atlas management interface.

Router	Local Interface	Local DLCI	Adtran	Adtran	Maps to Remote Router	Interface
R1	Serial 0/0	102	1/1	1/2	R2	Serial 0/0
R1	Serial 0/0	103	1/1	2/1	R3	Serial 0/0
R2	Serial 0/0	201	1/2	1/1	R1	Serial 0/0
R2	Serial 0/0	203	1/2	2/1	R3	Serial 0/0
R3	Serial 0/0	301	2/1	1/1	R1	Serial 0/0
R3	Serial 0/0	302	2/1	1/2	R2	Serial 0/0

FXS Setup

Using the following table, connect R1 and R3 to external modems, and configure the phone numbers on the Atlas 550. R2 may be optionally connected to the third FXS port.

Router	Port	Atlas 550(FXS)	Phone Number
R1	AUX	3/1	5556001
R3	AUX	3/2	5556002
R2 (Optional)	AUX	3/3	5556003

BRI Setup

Per the following table, connect your router BRI (or S/T> interfaces to the Atlas 550.

Router	Port	Atlas 550(BRI)	SPID
R1	BRI	4/1	SPID1: 51055510000001 5551000 SPID2: 51055510010001 5551001
R3	BRI	4/2	SPID1: 51055520000001 5552000 SPID2: 51055520010001 5552001
R2 (Optional)	BRI	4/3	SPID1: 51055530000001 5553000 SPID2: 51055530010001 5553001

PRI Setup

To implement PRI, connect router R2's PRI interface to the Atlas 550 PRI interface.

Control Device Requirements

NETLAB_AE control devices provide internal connectivity, console access, and managed power. Control devices are dynamically managed by NETLAB_AE and are not accessible or configurable by end users.

Control Device Resource	Quantity Required
Control Switch	3 Consecutive ports
Access Server	3 Lines
Switched Outlet Devices	3 Outlets

Control switch ports provide connectivity between devices in the pod. The Advanced Router Pod requires 3 consecutive ports on a control switch.

Access server lines provide console access to routers in the pod. The Advanced Router Pod requires 3 async ports on an access server.

Switched outlets provide managed electrical power, allowing NETLAB_AE and users to turn lab equipment on and off. The Advanced Router Pod requires 3 outlets on a switched outlet device.
