This chapter provides an overview of Cisco WAN and voice interface cards used in modular routers, and includes these sections:
The Cisco 3600 series is a multifunction, modular platform that combines dial access, routing, LAN-to-LAN services, and multiservice integration of voice, video, and data in the same device. The Cisco 3600 series includes the Cisco 3660 (see Figure 1-1), Cisco 3640 (see Figure 1-2), and Cisco 3620 routers (see Figure 1-3).
The Cisco 3660 has six network module slots, the Cisco 3640 has four slots, and the Cisco 3620 has two slots. Each network module slot accepts a variety of network module interface cards, supporting a variety of LAN and WAN technologies.
Each individual network interface on a Cisco 3600 series router is identified by a slot number and a unit number.
The Cisco 3600 series router chassis contains two, four, or six slots in which you can install modules. You can install any module into any available slot in the chassis.
For the Cisco 3660 router (see Figure 1-1), the slots are numbered as follows:
For the Cisco 3620 and Cisco 3640 routers shown in Figure 1-2 and Figure 1-3, the slots are numbered as follows:
Some modules have two small slots, labeled W0 and W1, for WAN interface cards. Figure 1-4 shows the W0 and W1 slots of the 2-Ethernet 2-WAN-card slot (2E 2-slot) module. You can install WAN interface cards into the small module slots, and serial WAN interface cards can be installed into either slot W0 or W1.
Cisco 3600 series routers have unit numbers that identify the interfaces on the modules and WAN interface cards installed in the router. Unit numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash (/), and then the unit number; for example, Ethernet 0/0.
 |
Note In the Cisco 3660 router, the fixed Fast Ethernet ports are located in chassis slot 0 and are identified by interface type chassis slot/unit number. For example: Fast Ethernet 0/0. |
Figure 1-5 shows a router with a 2E 2-slot module in slots 0 and 1. Two serial WAN interface cards are installed in the module in slot 0. One serial and one ISDN BRI WAN interface card are installed in the module in slot 1.
Unit numbers identify the interfaces on the modules and WAN interface cards installed in the router. Unit numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash (/), and then the unit number; for example, Ethernet 0/0.
Voice interfaces are numbered differently from WAN interfaces described in the previous section, "Unit Numbering." Voice interfaces are shown as follows:
interface type chassis slot/voice module slot/voice interface
For example, Slot 1, voice network module slot 0, is referred to as voice 1/0/0 (closest to chassis slot 0).
Table 1-1 lists the WAN and voice interface card options available for Cisco 3600 series routers with their minimum software requirements for supported IOS releases. Voice interface cards can only be used in voice network modules (NM-1V, NM-2V, and NM-HDV).

The Cisco 2600 series is a multifunction platform that combines dial access, routing, LAN-to-LAN services, and multiservice integration of voice, video, and data in the same device. The Cisco 2600 series has built-in LAN connections that provide a single or dual Ethernet port (depending on the model), one Ethernet, and one Token Ring port. Cisco 2600 series routers also include one network module slot and two WAN slots that accept a variety of network modules and interface cards. Figure 1-6 illustrates a Cisco 2612 router showing the network module slot and WAN interface card slots.
Each individual network interface on a Cisco 2600 series router is identified by a slot number and a unit number.
The Cisco 2600 series router chassis contains one slot in which you can install a network module. This slot is always slot 1.
Unit numbers identify the interfaces on the modules and WAN interface cards installed in the router. Unit numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Modules and WAN interface cards are identified by interface type, slot number, followed by a forward slash (/), and then the unit number; for example, Ethernet 0/0.
Figure 1-7 shows a Cisco 2612 router with a 2E 2-slot module in slot 1. One serial and one ISDN BRI WAN interface card are installed in the module.
|
Note WAN interface card slots (built into the chassis) are always numbered as slot 0, even if the interface card is installed in the slot labeled W1. |
Figure 1-7 refers to the unit numbers by the interface type chassis slot followed by a forward slash and the unit number. For example, first Ethernet interface, referred to as Ethernet 0/0
Voice interfaces are numbered differently from WAN interfaces described in the previous section, "Slot and Unit Numbering." Voice interfaces are numbered as follows:
interface type chassis slot/voice module slot/voice interface
For example, Slot 1, voice network module slot 0, voice interface 0, is referred to as voice 1/0/0 (closest to the chassis WAN interface card slots)
Table 1-2 lists the WAN and voice interface card options available for Cisco 2600 series routers with their minimum software requirements for supported IOS releases.
|
Note Voice interface cards can only be used in voice network modules (NM-1V and NM-2V). |

The following warning applies to the 2-Port ISDN BRI voice interface card (Cisco product number VIC-2BRI-S/T-TE).
|
Warning This equipment will be inoperable when main power fails. |
The VIC-2FXO-EU voice interface card and VIC-2FXO-M2 voice interface card have been approved to Common Technical Regulation (CTR) 21 for pan-European single-terminal connection to the PSTN. However, because of differences among the PSTNs in different countries, this approval does not in itself give unconditional assurance of successful operation on every PSTN network termination point. DTMF dialing is the default setting and is required for compliance to CTR21. Where pulse dialing is required for network compatibility, see the Pulse Dialing section for details.
In the event of problems, you should first contact your equipment supplier.
VIC-2FXO voice interface cards are available in several versions with interfaces intended for different geographical regions.
There are no hardware settings for connecting these voice interface cards to the public switched telephone network. To comply with national regulatory requirements, you must set call progress tones with the Cisco IOS cptone command to the values shown in Table 1-7.
To set call progress tones for a voice port, enter the following commands in global configuration mode:
