May 2002
Note Optical cards and Ethernet cards have faceplate rather than backplane
connections. E1000-2, E1000-2-G, and G1000-4 (Ethernet) cards
require gigabit interface converters (GBICs) that plug into the card
faceplate.
EC1-12 Card
The EC1-12 card provides 12 Telcordia-compliant, GR-253 STS-1 ports per card.
Each port operates at 51.840 Mbps over a single 75 ohm 728A or equivalent coaxial
span.
The EC1-12 terminates the twelve selected working STS-1 signals from the
backplane. The EC1-12 maps each of the twelve received EC1 signals into 12
STS-1s with visibility into the SONET path overhead.
DS1-14 and DS1N-14 Cards
The DS1-14 card provides 14 Telcordia-compliant, GR-499 DS-1 ports. Each port
operates at 1.544 Mbps over a 100 ohm twisted pair copper cable. The DS1-14 card
can function as a working or protect card in 1:1 protection schemes and as a working
card in 1:N protection schemes. The DS1N-14 card is identical to the DS1-14 and can
also operate as a protect card in a 1:N protection group.
The traffic from an entire DS1-14 card can be grouped and mapped to a single STS-1.
Individual DS-1 ports can be mapped to a VT1.5.
DS3-12 and DS3N-12 Cards
The DS3-12 card provides 12 Telcordia-compliant, GR-499 DS-3 ports per card. Each
port operates at 44.736 Mbps over a single 75 ohm 728A or equivalent coaxial span.
The DS3-12 card operates as a working or protect card in 1:1 protection schemes and
as a working card in 1:N protection scheme. The DS3N-12 card is identical to the
DS3-12 and operates as a protect card in a 1:N protection group.
