Cisco NIM-4BRI-S/T network switch module Accessories

The Cisco® 4000 Series Integrated Services Routers (ISRs) offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The Cisco 2- and 4-Port ISDN BRI S/T Network Interface Modules (NIMs) offer investment protection by providing data connectivity to legacy ISDN networks for the 4000 Series ISRs. IntegrationThe 2- and 4-port ISDN BRI NIMs enable branches to use legacy ISDN Basic Rate Interface (BRI) networks for data connections. Because they support industry-standard ISDN dialup capabilities, these modules can be deployed as the main WAN connection over ISDN BRI, dial backup over ISDN BRI, or a combination of the two. Each physical interface supports data traffic over two 64-kbps B channels, which can be automatically bundled together using Multi-Link Point-to-Point Protocol (MLPPP).Investment protectionThe 2- and 4-port ISDN BRI NIMs provide a cost-effective ISDN Dial-on-Demand Routing (DDR) solution for use with legacy ISDN networks. These NIMs are supported on the Cisco 4000 Series ISRs and uphold Cisco's commitment to providing customers with maximum flexibility and investment protection.Because the same cards can be used on all Cisco 4000 Series ISRs, the number of stocking units can be reduced and the NIMs can be redeployed from one platform to another.Shared features with Cisco ISR G2 Series ISDN modulesThe Cisco 2- and 4-port ISDN BRI NIMs offer many of the same features as the ISR G2 Series ISDN BRI modules and can thus be smoothly deployed without any additional training.A new feature is full online insertion and removal (OIR or hot swap), which was introduced with the 4000 Series NIMs.

Cisco NIM-2GE-CU-SFP= network switch module Gigabit Ethernet Accessories

Cisco® Gigabit Ethernet WAN Modules bring high-density Small Form-Factor Pluggable (SFP) and copper (RJ-45) 1 Gigabit and 10 Gigabit Ethernet (GE) connectivity to the Cisco 4000 Series Integrated Services Routers (ISRs). Providing maximum flexibility, the modules accelerate applications such as Ethernet WAN access, inter-VLAN routing, and high-speed connectivity to LAN switches and servers.The ports on these modules work as routed Layer 3 ports. Layer 2 switching between local ports on the module or between ports on the module and other ports within the router system is not supported. The port terminates Layer 2 trunks from externally connected switches, and Layer 2 trunk and VLAN information is not switched onto other ports in the system. The host router routes all traffic entering these modules.Cisco Gigabit Ethernet WAN Modules do not support Power over Ethernet (PoE).

Cisco SM-X-16FXS/2FXO= network equipment spare part Voice network module Accessories

The FXO port is used to connect to PBX or key systems, or to provide off-premises connections to the PSTN. It supports battery reversal detection and caller ID. The FXO port is also used to connect to analog Centralized Automatic Message Accounting (CAMA) trunks to provide dedicated E-911 service (in North America only).The FXS port is used to connect analog phones, modems, fax machines, and speaker phones to an enterprise IP voice system, so you can use them as extensions to your Cisco or third-party IP call-control system. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. The Direct Inward Dialing (DID) port is used to provide off-premises DID connection from the central office. It serves only incoming calls from the PSTN. Caller ID is not supported in DID mode.

Cisco 2GB DRAM Memory Accessories

Cisco 4400 Series Routers (4451-X and 4431) ship with a default memory of 2 GB of DRAM for the data plane, 4 GB of DRAM for the control plane, and 8 GB of flash memory. The 4-GB DRAM configuration for the control plane is derived by the installation of two symmetrical dual in-line memory modules (DIMMs) of 2 GB in each of the memory slots.When upgrading memory to higher densities, both memory slots must be populated with DIMMs of the same type and density for high system performance.The Cisco 4000 Series platform does not support the use of different DRAM densities in the two available DIMM slots or the use of only one slot.
