CH DS3 PPP/MLPPP 3-Port Line Module Description

The CH DS3 PPP/MLPPP 3‐Port Line Module provides channelized Point‐to‐Point Protocol
(PPP) and Multi‐Link Point‐to‐Point Protocol (MLPPP) network connectivity to a Total Access
5000 system by way of three channelized DS3 interfaces. Each channelized interface provides
connectivity for 28 DS1 channels.

PPP T1 Link to Ethernet

PPP operates at the data link layer and provides end‐to‐end connectivity for devices across a
point‐to‐point link. PPP is made up of a suite of protocols, including LCP, authentication, and
NCP (IPCP only), used to establish and maintain connectivity. The CH DS3 PPP/MLPPP 3‐
Port Line Module will forward frames from a T1 channel with PPP encapsulation to the
Ethernet uplink with a single S‐tag.
MLPPP groups can contain a maximum of eight T1 channels.

DS3 EFM 4-Port Line Module Description

The DS3 EFM 4‐Port provides four DS3 interfaces to the Total Access 5000 shelf. The DS3 EFM
4‐Port is designed for use as an end Ethernet First Mile (EFM) bonding interface that provides
aggregate Ethernet connectivity to additional Total Access 5000 Chassis or to NetVanta DS3
EFM Network Circuit Terminating Equipment (NCTE).
The DS3 EFM 4‐Port provides four DS3 signals consisting of digital data transmitted at 44.736
Mbps each.
NOTE
• The LMIO DS3 BNC Rear Panel must be installed prior to insertion of the
DS3 EFM 4‐Port into the chassis. In a 1:1 redundant configuration, the DS3
EFM 4‐Port modules must be installed in consecutive odd ‐ even slots.
• The LMIO DS3 BNC Rear Panel occupies two slots. Slot 11 cannot be used
since slot 12/SCM , SM A , and SM B slots are already occupied by the SMIO3
rear panel.
