The MIM-1G.SHDSL module uses regular telephone cables for connection.
n
Telephone cables have been included in the standard shipment package of
MIM-1G.SHDSL.
You only need a telephone cable to connect one port on a G.SHDSL module to the
PSTN network.
By far, the following ATM modules are available for the routers:
1-port ATM (Asynchronous Transfer Mode) 155 Mbps multimode fiber
■
interface module (MIM-1AMM)
1-port ATM 155 Mbps single-mode fiber interface module (MIM-1ASM)
■
1-port ATM 155 Mbps single-mode long-haul fiber interface module
■
(MIM-1ASL)
These ATM modules function in the system to provide ATM interfaces for routers,
supporting:
Two frame formats: SDH STM-1 and SONET OC-3;
■
Scrambling in data transmission;
■
Both line clock (when working as DTE interface), and internal clock (when
■
working as DCE interface);
Local cell loopback, local payload loopback, and remote loopback.
