Service card options:
As with the Compact T1 Channel Bank’s included T1 Controller Card,
the optional cards can be locally configured using the front-panel DIP
switches or the Command Line Interface (CLI). Manage them locally or
remotely by using the interfaces built into the Compact T1 Channel Bank
platform.
Front-panel LEDs on all service cards quickly inform of their status
and vary depending on the card you order.
Hot-swappable, the cards can be added or removed without powering
down the chassis.
8-Port FXS Card
This analog voice card enables up to eight direct phone connections
through the Compact T1 Channel Bank, delivering either outside phone
lines or on-premise customer business line services from T1 access
circuits. Up to 6 of these cards can be added to the channel bank for
48 Foreign Exchange Station (FXS) connections.
Automatic impedance balancing provides echo-free service
connections for a wide range of customer equipment and line conditions.
V.90 transmission ensures optimal dial-up modern performance.
The 8-Port FXS Card supports Caller ID, three-way calling ID,
distinctive ringing, and E&M signaling conversion.
8-Port FXO Card
The FXO Card provides high-density provisioning of reliable Foreign
Exchange Office (FXO) or Direct Inward Dialing (DID) telephone services
for T1 access circuits. You can add up to 6 of these cards to the chassis
for 48 connections.
The FXO function sinks battery current and detects ringing voltage
originating from a central office or PBX line, so you can extend dial tone
and calling features to remote locations. When configured as a DPT
interface, the channels sink and detect forward and reverse line current,
emulating the functions of a central office DID line.
The 8-Port FXO Card supports Caller ID, calling party disconnect,
distinctive ringing, ground start, and E&M signaling conversion.
As with the FXS Card, the FXO Card’s automatic impedance balancing
provides echo-free service connections for a wide array of customer
equipment and line conditions. V.90 transmission ensures optimal dial-up
modem performance.
4-Port OCU-DP Card
The Office Channel Unit Data Port (OCU-DP) Card essentially provides
the electrical and physical termination of a 4-wire Digital Data Service
(DDS) baseband connection that interfaces with a remote CSU/DSU. Up
to 6 of these cards can be inserted into the channel bank chassis for up
to 24 connections.
Use the card to link up to four CSU/DSUs that are connected to remote
bridges, routers, and other network devices and provide standards-based
DDS access for service subscribers or users at their data terminals. The
4-Port OCU-DP Card features scalable, independently configurable,
synchronous data service rates from 2.4 to 64 kbps.
In addition to interconnecting lower-speed serial synchronous DTEs
and terminating DDS circuits, you can use the OCU-DP Card alongside
DS0 voice, fractional T1 data, or other cards in the Compact T1 Channel
Bank for a truly integrated solution.
8-Port ISDN Card
This card enables you to deliver high-density, standards-based ISDN
Basic Rate Interface (BRI services over one or more T1 or DSL access
lines using TDM or ATM transport. This means you can deploy ISDN
voice, data, and real-time video applications as part of any integrated
broadband service. For instance, you can economically bundle ISDN
with all other services at 64 kbps or 128 kbps over T1 access lines.
Up to 5 of the cards can be used in the chassis for a maximum of
40 ISDN BRI circuits.
Configure the card as either a line unit line terminal (LULT) for making
connections to ISDN switch interfaces at the central office, or as a line
unit network terminal (LUNT) for the customer premises. The 8-Port
ISDN Card provides direct NTU service demarcation for ISDN video
conferencing, 128-kbps dial-up Internet, point-of-sale terminals, and
ISDN Centrex or telephone applications.
4-Port T1 Card
Add ports for up to four T1 lines with this card—whether you need
to backup existing T1 line connections or add connect additional DS0
channels. This way, you can economically provide and expand your T1
bandwidth with full non-blocking digital cross-connection of all timeslots
to any Compact T1 Channel Bank service card.
Service providers or enterprise network managers, for instance, can
use the card to cost-effectively add and expand network or drop-side T1
bandwidth. The card supports a number of network access technologies,
including fractional and full T1 data and voice trunking.
Combine the 4-Port T1 Card with the Compact T1 Channel Bank’s
already-installed T1 Controller Card to support up to 18 T1 access lines—
which is enough for most small- to medium-sized businesses, multi-tenant
units, fixed or mobile wireless backhaul applications, and end-office uses.
Working with the T1 Controller Card, the 4-Port T1 Card provides local and
remote management functions.
Up to 4 of these cards can be added to the chassis for a total of 18 T1
connections (taking into account the two connections provided by the T1
Controller Card).
2-Port V.35 Card
This service card enables you to set up connections to high-speed
serial synchronous data terminal equipment (DTE) devices, such as
routers, Frame Relay access devices (FRADs), and videoconferencing
equipment. Use it, for instance, to integrate Frame Relay or private V.35
services with voice and Internet access over T1 lines. The card features
integrated T1 CSU/DSU functionality.
The 2-Port V.35 Card provides scalable high-speed data service
capacity to meet growing needs of users. Each of the card’s V.35 ports
supports any n x 56-/64-kbps rate up to 1.536 Mbps, and both ports can
operate simultaneously at any supported speed.
Flexible clocking enables loop timing from any T1 line and provides
system clocking to the connected DTE. It also supports adaptation and
transport over TDM facilities.
Add a maximum of 6 cards to the Compact T1 Channel Bank chassis
for connections to 12 fractional T1 V.35 connections from two T1 network
connections. Depending on your application, you’ll need to order one or
more V.35 data cables.
IP Router Card
With its own dedicated processor, this card offers the performance
and expandability of a dedicated router in a modular format. It’s ideal for
providing high-speed Internet and Intranet connectivity to small and
medium-sized businesses, as well as remote- and branch-office users.
The IP Router Card offers powerful IP and IPX routing, 3,000-packets-
per-second throughput, and Layer 2 bridging plus networking security
and management capabilities. All it takes is a single unique IP address
to configure and manage a number of IP Router Cards installed in the
Compact T1 Channel Bank chassis. You can add a maximum of six cards
to the chassis, and each card acts as a single 10-/100-Mbps Ethernet
router with autosensing abilities.
Because the IP Router Card uses Multi-Link Point-to-Point Protocol
(ML-PPP) for bandwidth scalability, you can support the growing needs
of your customers by offering more than just one or two T1s—multiple
T1 facilities can function as a single IP WAN interface, providing up to 60
DS0s of bandwidth or up to 24 WAN connections per a card for multipoint
networking. This flexibility enables service providers to target multitenant
